If you aren't to bothered about weather but want lots to do, how about a holiday village, I think FC have them in Lanzarote, Turkey, majorca, and are about to open one in the Red Sea. Also their are many large resort hotels on Turkeys Med coast (Side, Alayna, Belek etc) this is the only part of Turkey that is considered an all-year-round coast.
Not been myself but from what I read on hear holiday villages are great for people who like lots of activities on their hols.
