I loved Sitges, it is an incredible place, the Las Ramblas (their main street) is great - the beaches are fab. Now do note, Sitges is a gay resort, Mr. Bear - he didn't like it as it is very gay.
I can assure you though it was the best holiday (apart from Mr Bear giving out ) I had in years - it is so colorful and the characters I met were fantastic fun... I can also assure you that it is the safest place I have ever been, the Las Ramblas was great fun. We also went to Barcelona, and you know the Las Ramblas was very seedy at night - loads of prostitutes touting business...
I am envious of your trip if you go...
