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.
The balcony view is partially obstructed by the life boats if you are looking straight down! That wasn't mentioned when we booked but I was surprised to walk outside and when I looked down, I could not see the wake of the ship. Looking straight out, there is no obstruction. It is a little bit of a walk from the elevator but we experienced virtually zero noise while in our cabin from foot traffic or other floors.
