I've been on my own two of the times that i've been there , been with a friend as well, sooo easy to meet people there .. life's too short to wait around for my friends to go with me.. they couldn't keep up with me anyway, ha ha!
You will LOVE it... best time to go is beginning -mid/ end Sept for the closing parties.
there is really no other place like it.... i like my nude bathing too and lots of beaches for that..
sorry for hijacking with the ibiza excitement, but it is my favourite place on earth! I'm getting the jitters just thinking about it!! wheee!!!
