New rules have stated you can go into the actual "Island" for free and at any age, but it now costs to get into the separate clubs (a point on your MYW cards). However, it is not really a place for kids - there is a lot of drinking going on - they serve alcohol on the streets during the nightly celebration and I believe most people here agree that it's definitely a bad idea to let all ages into PI. For kids, there's really not much to do - there's a Superstar Karaoke Studio and some carnival games, but mostly it's just clubs. The Adventurer's Club and Comedy Warehouse are the tamest things there, however, the jokes are quite adult. In the end, it's up for you to decide. Have fun though!!! Whether or not you take the kids, you'll have a blast
If you ever have an "adult night alone" I suggest jellyrolls over PI anyway. Believe me, when you go, you'll see why!
However, with the new 'open access' policy, it's starting to get as bad as Main Street; crowds of kids with nothing to do but roam the walkways. And we can find that kind of atmosphere anywere on-site.
and the odd dance... however, when we went it wasn't very busy. We were also shocked that you were allowed to drink on the "street" there too. And, not only were we allowed to bring our outside drinks into the clubs, they were our ticket to the front of the line. We are from Canada and our laws are quite a bit more strict. Anyway, we had an awful time getting into Adventurer's Club and it kind of ruined our nite (even though we were both of age, and I look OLD!). We had a couple of drinks and danced somewhere else but it wasn't much fun. We had more fun when we went over to Planet Hollywood which isn't on the Island, even though we have one about 20 minutes from home. This year, we plan to go to the Boardwalk (ie. Jellyrolls) since we have heard so much about it and didn't get a chance to visit last time!
