Ibiza is out of order expensive because it is is loaded with rich British
kids and their bars and loud, really loud
music. The
marinas cater to the mega yacht types, not sailors. The
anchoring field isn't even a convenient
dinghy ride away, and it is primarily a
grass bottom. Any
wind at all and it's trouble in there with
boats crashing into each other.
San Antonio is an equally party-oriented town, but great for
anchoring.
You can hear the low end
music from both of these towns from 10 miles off of the island.
