We went on a 10 day holiday to Cyprus with Thomson last October, when we went to reception to request keeping the room (as it was a night flight home) they informed us we were booked in for 14 nights,when I told them only 10 nights, they said thomson had booked for 14 nights...so really I suppose we could have stayed and paid for another flight home.

We found a 10 night stay was a good option, as one week isnt long enough and sometimes two weeks is too long.
Generally though we have two weeks in June and then a week in sept/oct if money allows
