I stay in San An bay every year and I love it, partly just because it's tradition now but also because it's just got a nice, easy going vibe about it.
The number one downside is the taxi fare over to the clubs which did make a dent in the pocket two years ago when it was just me and my boyfriend and we went to Pacha, Space, Sankeys and Ibiza Town, but last year with 4 of us it was much more managable.
And anyway, as a few have mentioned, this year it's going to be Privilege, Amnesia, Eden (maybe with one evening in Ibiza Town), I don't really have a reason to go that far anymore now Space isn't there and Sankeys isn't pulling me in.
