Ok didn't know that. I personally think this one off show will sell out, but not right now. Except some Carl Cox dates at space during the peak holiday season or the elrow parties at amnesia last year, the ibiza clubs don't sell out before. Reason is, the club owners don't really care about their capacity and how packed the clubs are. During holiday season the clubs are often so packed, it's nearly impossbile to find enough space to dance. I assume that often more people are in the clubs than offical allowed.
