Stay away from San Antonio, except for going to the sunset cafes (Del Mar, Mambo, etc.). Buy your pills in Barcelona if you can: just got back, and they were $5 for the cleanest/purest MDMA around. Avoid the "cheese clubs" if possible; Es Paradis was one of the worst clubs I ever went to. Check out Amnesia and Space: excellent vibes here. Rent a car (around $30/day) and take the wrong road; you never know what you may find (i.e. amazing secluded beaches, restaurants on top of seaside cliffs). DON'T drink the water and watch what you eat: the "Ibizan flu" can easily ruin several days of your trip. Avoid touristy restaurants; crap food is in abundance on the island. Hmm; this is all I can think of at the moment! P.S. Oh; and make sure you spend a few nights in Barcelona - a wicked city!
