Its more about music than hating San An.. I stayed there the first time I went to Ibiza many years ago and I loved it. That was 10 years ago though when I loved Trance. There are a few smaller places there now that have different music but I think its more convenient if you like house and Techno or if you want to be near Space to stay in PDB and San An is more geared toward trance and hard house. The problem with San An is it was featured on a programme a few years back making it look like Blackpool with drunken yobs and slags but as far as Im concerned theres yobs and slags everywhere its just the ones in San An have bad musical taste
I'm not sure about the Trance thing in San An?! Garlands, Wonderland, Pukka up, Miss Moneypenny's, SuperFreq etc etc all in San An this year.
You're right about the San An perception through the TV programme Ibiza Uncovered. It just showed all the 18-30 bar crawl brigade, getting scattered seeing how many shags they can have in one night before throwing up everywhere.
Whilst it's not quite that bad, this is all down one area called the west end. Either side of the west end, the famous sunset strip, Mambo, Savannah, Cafe Del mar etc are pretty chilled. I also like the bars along from Bar M - Bay Bar etc. Really chilled atmosphere, big comf chairs\cushions etc etc.
If you stay in San An, its still not too far to get to Pacha, Privilege, Amnesia etc.
