I went there last year with 7 others - we went in one of the cheapest weeks, and stayed in the cheapest villas. Cost us about £40 each for a mid-week break (4 nights)!
We did a food shop before we got there, spent half the time in the pool, went out cycling for lots of the time, and then did a couple of other activities like crazy golf, badminton, bowling etc.
Was a really really great week away, I am definitely going to go again sometime!
