the short answer is NO!!!!! if you want to go clubbing
only pacha is really open at weekends, with a few exceptions, the crowd will be mainly spanish, and will have a very inderground feel to it. some bars will only be open at the weekends and thats it.....
But if you don't wanna go for clubbing, its a nice time to go, the weather can be very pleasant and the scenary is colourful. Many ibizan residents say that this is there fav time of year!!!.
merry xmas Rob
