Sailed on the Adventure of the Seas, out of San Juan.
Checking in at San Juan was easy, even though there were a lot of people there and in line, we (my wife & I) were through it all and on the ship in 15-20 minutes.
We had a balcony room. Room was clean, on 7th deck. Bathroom wasn't real big, but enough room and everything was clean and worked fine. We had our bed set up as a king bed, also had a sofa in our room. Closet, desk, with TV and fridge, plenty of room for the 2 of us. We were mid-ship, 7th floor was quiet, not too far from anything. The dining room for us was on 4th floor, the Windjammer buffet dining room was on deck 11, and Royal Prominaide was on deck 5. We walked the Prominaide every day/evening, and often stopped at the cafe/starbucks to get drinks or a snack, was included with our beverage package. Even ate a light breakfast there one morning, but they didn't have much out for breakfast. They almost always had small sandwiches and pizza by the slice.
Was my first cruise, 2nd for my wife (went with her Mom a few years earlier). We had a great time, food was excellent, we never paid extra for any of the meals, the main dining every night was great. We had our own table, often ordered several appetizers and desserts. Service was excellent. We had a non alcoholic drink package, called the refreshment package. We ordered non alcoholic pina coladas, mudslides, and other drinks. Bar tenders were good about helping us pick drinks. At times the bars on the ship were busy, not too bad, and you could sit out by the pools and get wait service when you wanted too.
We did an excursion at every port. I would recommend doing your excursion early in the day, then return to the ship, clean up, eat, change etc, then do something else in the afternoon like shop or go to beach in the afternoon.
St Thomas & St Kitts are kind of similar Islands, mountainous. We did a sightseeing tour on St Thomas. Went way up to the highest point. Was a nice view, and made a couple stops where we could get souvenirs or drinks. Great views, since we did a morning trip, left us time to shop downtown in the afternoon. For us, we ended the tour at the downtown area, then did some shopping. We got a taxi ride back to the port area for $4 per person, was easy to find a ride.
At St Kitts we did the kayak and snorkeling tour. Was well run, traveled to the far side of the island, and kayaked with the current, down the beach. Wasn't too windy or rough, so it was nice. They served us a few pieces of fruit and some water after we finished, before the bus took us back to the port. Shopping was walking distance from the port, the vendors have all mostly the same stuff, and are a little over eager to get you to look at their stuff.
Day 3 We had a fun day at sea, the belly flop competition is a must see, pretty funny. I have to mention that our cruise director, Mercedes, was awesome and always entertaining.
Day 4 - Curacao is a very nice island and port, free wifi was available. The beautiful town is walking distance to the port. They have a good economy, so the merchants weren't always after you like other islands. We did an aqua boat tour and snorkeling there. It was ok, but it is always very windy in Curacao. The mini boats worked ok, the tour could have been a little more organized, and the seas were pretty rough. I was glad we weren't in a kayak like some of the others, but wished we were on Jet skis. The snorkeling was crowded, but was in a good area with plenty to see.
Aruba is a small, dry island with great beaches. We did the best of Aruba tour, so we saw most of the famous spots on the island. We had a nice air conditioned tour bus, with Juan Jacobs as our driver. He was very good. We did the aloe factory tour as part of it, not a lot to see but informative. Chance to buy aloe products at their store after the tour. Once we got back to the port, we changed on the ship, and then walked to the bus stop to take a bus to the beaches. Took a little asking to get on the correct bus, but was only $5.20 for both of us to take the bus. We got off at Eagle beach. If I would do it again, I would have stayed on and gone farther away from the port, more toward the California lighthouse. The beaches are similar, but better snorkeling farther down the beach. We could have taken a bus back to the port (9:30pm on board time), but we opted to walk back along the beach. Some of it had a boardwalk, and the sun was setting, so it was really pretty. It's a couple miles, so packing light was important. We like to walk, could easily take the bus at any point, there are a lot of places it stops.
Cabin with a balcony is the only way to go!
