I dunno how was last year because I skipped it. This year seems busy. I was in Ibiza at the end of June, this season was picking up. However, Space, Pacha, El Divino ,manumission and even Amnesia were packed with some space to move . year 2001 was better but I can't really tell beacuse in 2001 I went in peak season (late August).
This year was my first on the island and I was suprised. Although we went out in the middle of June, I thought that the begining of the season would have kicked in and the island would be rammed. It was no where near as busy as I expected it to be.
I was last year in Ibiza late june early july... comparing it to my other 3 years before, was it not really busy... (although I can't compare with 2 of the 3 years, because those were in late july)
I am now looking around for last minute holidays to Ibiza (yeah yeah, I simpy can't resist it), and there are enough possibilities.... although I remember from my first 2 years that it was fully booked during the whole summer.
