Although it's basically the same ship, I tend to like the Allure better than Oasis primarily for the entertainment. Oceanaria is a much more exciting show in my opinion compared to Oasis of Dreams and Blue Planet the same versus Come Fly with Me. I will give the Oasis Frozen in Time ice show some props against Ice Games on Allure but Allure has the How to Train your Dragon ice show as well and it's very good. What makes Frozen in Time a winner to me is the part where the guy creates images in a sand box which are projected on a big screen. That saved the show from boredom as I'm not a huge fan of ice shows in general.
Itinerary is as follows: Depart Saturday at 5pm and have the next day at sea before arriving in Labadee Monday AM. After a full day in Labadee, you leave and dock in Falmouth the next day. After leaving Jamaica, you have another day at sea until you get to Cozumel. After leaving Cozumel, you a final day at sea before arriving back in Ft. Lauderdale. This itinerary is very attractive for me. I liked the days at sea spread out throughout the voyage versus the clumps of sea days during the Eastern itinerary. Good places to watch the sail away is the area over the bridge in front or the public aft aqua theater viewing decks located on decks 7,11,12, or 14. The ship docks most often with the starboard side facing the port and always on the Western itinerary.
Other points to note:
Oasis doesn't offer a Cruise in Review DVD but Allure does. This DVD has content from all of the major events during the cruise (Belly Flop Contest, 70's Disco Party, Love and Marriage and Quest shows). I bought the DVD on Oasis thinking I was going to get this but all I got was a DVD with general information on the ship. I called in they said that they tried to do it on Oasis but they couldn't keep up or something. However, they do produce it on Allure. Go figure.
Another thing that nagged me during the whole cruise was one of the Flow Riders had only half of it working. It was the boogie boarding one on the starboard side and I heard it was down the previous cruise and was going to be down for another week after our cruise. Made for very long waits to do the boogie boarding. Had a hard time understanding how a main attraction could be half way working for 3 weeks.
Food was pretty good in my opinion for all meals. We only ate in the MD room once and I enjoyed it. I suggest visiting a variety of places when cruising on Oasis. Some suggestions are Johnny Rockets for breakfast (fee free). Solarium Bisto and Central Park cafe' for both breakfast and lunch. The Windjammer is almost always very crowded and at times hard to find an open table. If you go to Izumi (sushi specialty restaurant), they offer you Avian or sparkling water to choose from but I didn't know they charged you $4 for it until we got our bill.
We bought the premium drink package and it paid off for us. Was able to try a greater variety of drinks knowing that if I didn't like it, I could just order something else after 5 min elapsed. The drink of the day almost every time was way too suite and I could barely detect that it had booze in it.
Stateroom: We had adjoining Jr. Suites on deck 8 starboard mid-ship and the location was great. Our rooms were on the bump of the ship (8642 and 8644) thus had a larger balcony than the advertised 80 sq ft for the JS. I estimated that it was more like 120 sq ft so when we opened the divider, we had 240 sq ft of balcony to enjoy. Those rooms also had an adjoining door located near the balcony side of the room and a walk in closet which was a nice feature. The bathroom was a bit larger than the regular one and had a shower tub which really great water pressure. Deck 8 gives you quick access to Central Park providing enjoyable scenery as stroll to another area of the ship.
There are only 2 outlets located on the vanity across from the bed. The way they are located, some things could not be plugged in but we brought a 3-way outlet splitter and that helped. HOWEVER, at the end of the cruise, I found another outlet behind the bed that could have been used for chargers, CPAP, hair dryers. You might consider bringing a 6 ft extension cord to utilize that outlet and be able to sit at the vanity.
Port of Call: Labadee - Always enjoy going there. It's been built up a lot during the last several years. The Dragon Coaster is a good thrill and $21 for the first ride (up to 2 riders) and $10 for additional rides. The zip line is too expensive to me but a big thrill if you don't mind dropping $89pp for a short training rider and the main attraction one. There are several beaches/coves. Adrenaline Beach is good if you want to stay near the shops and their biggest bar. Much of the beach has a lot of rocks and slimy yuck under the water but they profess that if you go way over to the right, you don't have as much. We visited Columbus Cove for the first time and found that to be the best virtually rock free area with ample shady spots. It's a bit of a hike to walk there but there's a ferry that you pick up from the pier next to the ship that takes you across the bay close to the spot. Lunch as bars are spread out so each main area offers both food and drink.
Falmouth: The port shopping area is nice and clean and has plenty of shops. There are some places to eat but not the local type food you would hope for. If you venture just outside the port compound, there are a bunch of local jerk chicken etc. vendors just across the street. You may get pestered to buy stuff but you just have to press through that. We did the Dun's river tubing, boat cruise, and Dun's River Falls climb combo ($139pp). This included a nice buffet lunch and the took the entire day (7+ hours). We didn't have time to shop before and had only 10 min when we got back before the all aboard. The cruise part of it was something I could have done without but the cheaper version that didn't include it was all booked up. BTW - it's said that the ship won't leave without you if you booked the excursion through the cruise line.
Cozumel: Port shopping area has plenty of souvenir shops. You can bargain heavily at some of them especially the ones upstairs above the duty free ship. Those vendors up there will have guys at the bottom of the stairs trying to entice you up there. They are desperate so you will be surprised at the hard bargains you can drive up there. We bought a hand made leather purse for $70 that started out at $120. I probably could have gotten it for $50 if I held out a little more. Take their price and offer half and negotiate from there. Start to walk away and they almost always drop the price more. You can get a voucher on the ship for a free taxi to the downtown shopping area. Cost you about $8 to get back. Loads of shopping and restaurants down there. Be careful of the sometimes confusing currency conversions as they are often in Pesos or may try to hide high prices with a free appetizer.
There's a Senior Frogs place at he port shopping area. Real fun and energetic place with games, and music. You can rack up a huge tab in almost no time there. A girl came by and offered some weak shots at $7 for two. The next thing you know, she's pouring 6 shots between you and yours and you're $21 in the hole without even blinking an eye. The giant funnel drinks are very expensive and you would think one would get you buzzed but it's very weak. You could drop well over a $100 easily. Food is decent.
Disembarkation: Always slow and depressing. I highly suggest paying the $20pp for the luggage valet service. They take your bags the night before return and you don't see them again until you reach your home airport. They provide you boarding passes and everything. Just remember that the deadline to register for it is by the end of day 4. They will provide you the form in your day 2 Cruise Compass pack.
