In October 2004 me and few friends went to lloret de mar, but unfortunately it wasnt what i was expecting. because it was out of season, it was really quiet, and thought that a few more people would be about.
If you go as late as oct then the pr's will be very persuasive trying to get you to go into their clubs.
The nightlife is pretty good i found. Start off at mobys as they normally give you voucher buy one get one free, and then off to a club tropics, 3 floors of bliss.
If you want any more info let me know.
Ps. if you you want a nice meal and very cheap go to the mexican place on the seafront. Very ncie people. Apparently we broke the record for drink.
