Awesome Ship!!! You really don't have to get off at the ports!!!
Jus returned off the Oasis May 21, 2016 sailing. The ship is something to behold!!! The ships condition is in top shape. The staff, service, entertainment and food is the best we've had in 11+ cruises. The ship is so well laid out, that even with 5000+ guest, and 2000 more workers onboard, the ship never feels crowded. Our room was on the 14th floor overlooking Central Park. This was a good location to get around the ship, but there is nice from deck chairs starting at 6:00am. There's also music from the Caribbean Band, Heat Wave in the afternoons, so if you're trying to take a nap to take in the night life, it will be hard. The noise didn't take away from our vacation, but this was the first cabin we had that didn't had cabins above or below, and we don't know how we missed that, but we wouldn't select that deck again (we would do another Central Park cabin on deck 12 or 11).
The ships pools or hot tubs were never crowded to where you couldn't enjoy them. Their Production of Cats was Broadway level, and I recommend you see this, along with the other shows (Frozen in Time, Come Fly with Me, and the Aqua Show) onboard. The adults only Solarium was our place for breakfast most days, and the place to relax. We ate dinner in Chops Grille and the food was really good, and as we remembered it from our previous Royal cruise. IF your a drinker, get the drink package (Premium or Ultimate). It more than paid for itself with the unlimited drinks.
We made this cruise mostly about the ship, and didn't do any excursions except to stretch our legs at the port and port shops. This cruise was an awesome experience, and we've already booked another cruise on the Oasis when she comes to Port Canaveral.
I highly recommend trying out the Oasis, or one of her sister ships, the Allure or Harmony.
