1. Bora Bora- indescribable unless you have gone. You "MUST DO"!!!
2. DC10 Monday Mornings- lets just say that seven hours passed in the blink of an eye
3. Sundays at Space- I had more fun there at night versus day, but both are fantastic.
I would say Amnesia on Thursdays for a trance lover as well, but every time I go (and I always do for PvD and Tiesto) it is SOOOO jam packed and hot as hell. I feel really uncomfortable and chlaustraphobic. They do have this amazing CO2 chute that pumps out a blast of icy cool fog every once in a while, but not often enough.
Honorable Mention? I had a blast at Hed Kandi which was held at El Divino (seems like people here dis on Hed Kandi, but I had a smashing time). Also Ancient People, but unfortunately that place will be no more
I might get a lot of flack for this one, but SORRY Salinas beach is not worth it. I had never been to a nude beach so I wanted to check it out. First off, it was SO far away from our apartment in Ibiza Town... secondly the people there were pissy and when we weren't looking they took our stuff and put it in the trash.
Wherever you are in Ibiza... have the time of your life. It won't be hard to do so!!

ps. I know there is lots of unforgettable sight seeing too.. but I am not the one to ask about that... I mainly go for the music and party atmosphere
