Vegas will never compare to Ibiza for clubbing. Vegas is a completely different place. A place which is fun and has loads of things to do but Ibiza is a special place.Musically and culturally, it's a magical place. I thought the clubs in vegas ain't all that. No underground feel to them, just posh places with loads of effects. This is why I don't think Clubbers will ever take vegas serious as a clubbing destination no matter who plays there. Ibiza with its strict rules on closing times etc is starting to fall behind places like Berlin on the clubbing front. You can club in Berlin 24hrs a day which is something you should be able to do Ibiza.
