I've been on the Princess Grand class ships only and really like the size of these ships and always said I would be afraid to try anything bigger. When I first heard about the Oasis I wondered how the "crowds" would be. Are the buffets overcrowded? How about the shows and even the dining rooms? I'm sure they staff
assenger ratio is the same so hopefully staff don't become over burdened.
I know on the Princess ships sometimes things can get busy (popular shows, pools, buffet lines, elevators, etc...) but overall I never had an issue as things do move along quite well. I'm assuming with there being so much to do on the Oasis, that the crowds would be distributed fairly well and you might not even notice it.
All that being said, I think I would love to try it once just for that “wow” factor but don't think I would want to do it all the time.
