This was our second cruise and it was also our honeymoon. We weighed going on cheaper cruises but other half insisted that we go on "the big boat". I'm glad I listened to her. Even though it cost much more than everything else we were looking at, the Oasis really was worth the money.
The ship was always immaculate and it feels like you're on a new ship. The layout and the decor were aesthetically pleasing and while the ship is large, no question about it, it was never really all that far to get where we were trying to go. The staff for the most part was very helpful and friendly, although for the second time, we had a bad experience at the spa on a Royal Caribbean ship (we will get to that in a minute).
Specifically, one of the best things about this ship is the way the cabins are laid out. Supposedly, the sq footage of the Oasis balcony rooms is a little smaller than the balconies on other ships. However, that is either inaccurate or the way the rooms are arranged more than makes up for it. The shower in the bathroom has an odd shape that affords a little more room in the shower stall and the vanity in the bathroom is shallow which makes the bathroom feel bigger. In the cabin, again, the vanity is shallower and gives you more room in the cabin and the closets are laid out in such a way so as not to take up too much space from the living area in the room.
We had a package for the specialty restaurants and by far, the Chops grill was the best. We also went to Izumi and that was pretty good. Giovanni's Table was just ok. The food in the main dining room was good and of course, if you're familiar with Royal Caribbean, the Windjammer is the Windjammer.
There are only two issues I really had with this cruise. First is that the ship, while not being obnoxiously large, is big enough to affect the experience and interactions with the staff, probably because of the number of guests on board. On our previous cruise, we were able to familiarize ourself with the bartenders and some of the staff on board. On this ship, at almost every bar, there is a constant stream of people and the bar tenders don't seem to have the time to get to know the passengers. Also, the cruise director staff seemed to always be en route to the next event and didn't really have time to meet the passengers. On the whole, the cruise experience just felt impersonal compared to our previous cruise.
The second issue we had was at the spa. The spa itself was absolutely gorgeous but the staff just seemed more qualified to sell you a treatment than to provide it. We had a couples massage done and while oils they use seem to be very nice, as far as the actual massage, you could probably a significantly better massage done for a quarter of the price at any massage parlor on land. Also, 15% gratuity included means that they aren't necessarily motivated to do a better job. Sadly, this was the same as our experience on our previous cruise which means we will not be getting massages on any future cruises.
On the whole the cruise was still a great experience and we are excited to go again but the lessons learned are go on a smaller ship and don't go to the spa. Instead, spend the money at the bar or at the specialty restaurants.
