San Antonio, Ibiza. I went there for two weeks with my wife in 2001 and the complex was awful. The people were really, really inconsiderate and the family above us used our veranda as an ashtray and a rubbish tip! Every two seconds I was being offered weed or E's and it was generally pretty raucous. That taught me NEVER to go cheapy, cheap ever again.
What's the strangest thing that's happened to you on holiday?
