I will be doing my second cruise on the Oasis next month. I have also cruised on the Allure.
Those are great ships. I recomend them for everyone. There is a lot to enjoy and there is plenty of fun for people of all ages.
If there are youngsters aboard they will be doing their own thing and it won't keep you from enjoying your experience aboard this wonderful vessel.
Enjoy your cruise.
