We sailed Allure this summer after doing 4 Disney Cruises. Our teen daughter declared it her best vacation ever, so Royal does do older teens and young adults very well.
Some other differences you'll notice on the Oasis/Allure...
- You can make reservations at certain dining locations (Like Chops, Izumi, Sabor) ahead of time online
- You can and should make reservations for certain shows ahead of time online. This includes the main theatrical show, the diving show, and especially the comedy show
- Consider purchasing the soda package. If you don't, your drink options are water, tea, lemonade and coffee. Some locations will also have flavored water, and there is juice at breakfast. Allure and Oasis have the Coke Freestyle machines. The drink packages also work on the private islands
- Go to a website like the Royal Caribbean Blog - you'll find Cruise Compasses there for similar sailings and you can scope out activities. Don't overlook the smaller ones like cupcake decorating!
- Plan to go to The Quest! It's usually on the last night. Wear underwear.
- There are no Wave phones, so decide whether or not you want to use cell phones on the Wifi plan to contact each other.
- There are many more pools on the Oasis class ships. The sports pool will host a water volleyball tournament that is very popular.
- The clubs go much later at night on Royal, and there is a lage variety - salsa, jazz, acoustic, dance, etc.
- There is lots of trivia. The more people you have on a team, the better
- There is free ice cream like on DCL - it is located in the cafe by the Flowriders
- There is a lot of live music around the ship - poolside, in Central Park, etc.
- The buffet closes mid-afternoon and re-opens for dinner - unlike DCL, I believe it is an actual buffet at dinnertime
- There are lots and lots of photo opportunities throughout the cruise - more so than on DCL
- The shopping is totally different. Think high-end bags, jewelry and clothes, as well as popup sales on gold chains, jewelry, watches, etc. Avoid the tshirt sale - it is like Black Friday at Walmart.
- Starbucks!
