I love Turkey - the Turkish Riviera is very nice and there are still some quiet places to visit. Or you may go to Bodrum (south-west of Turkey), nicknamed 'Bedroom', with fancy discos, bars, good restaurants and luxurious hotels that are not too expensive. It is very hot though in the summer, you may want to check into one of those luxurious hotel with a pool, situated next to the beach (you can do some diving as well)!
If you like some culture, why not try out Marrakesh in Morocco with its ancient
souk (market place) where you can still see people getting their teeth pulled (eeks), little monkeys, snakes, fortune tellers etc. Lots of nice stuff to buy - leather bags, pottery, cloths, jewellery etc. You could consider staying in Agadir, a beach village at the Southern coast of Morocco. You can ride on a camel on the beach and make some nice - organized - trips from there by bus or rental car.
Have a wonderful holiday a luckyducky!
BTW, it's also hot and humid here in Good Old Amsterdam (Holland)... the people here are dancing in the streets because Holland won, lol.
