Okay, what specifically did you want to know?
A more general review of the teen facilities
Oasis of the Seas is Royal's second-latest ship and the first in her class. The teen facility onboard is still fuel, although I haven't heard much about the events. I am told however, that the sound and effects are superior when compared to the rest of the fleet.
The usual club session occurs from 10 - 1am for the 15-17 crowd. Other events around the ship with the teen club can be found in the daily compass.
As far as themed parties goes, that is at the discretion of the teen host onboard. If you choose to create your own themed party with your new friends that's always a lot of fun as well.
As with the rest of Royal Caribbean's fleet, a 1am curfew applies to all under the age of 18.
