Well a big difference is the kids are able to come and go as they please. No need to check them in or out.
My teens report that there’s always something going on and it doesn’t always match what’s listed in the navigator. Magic shows, team trivia, bingo, video games (such as Mario Kart and Rock Band), scavenger hunts, things like that. They do usually plan a flash mob to occur during the pirate party and have several practice sessions. But it seems like if the teens aren’t into doing the planned activity the staff will pivot to something else. There’s usually a farewell dance party.
Edge has a private pool area open at limited times
On Castaway Cay there is a teen beach area that is open to both vibe and edge guests combined. It has volleyball and hammocks amongst other beach features.
