I am planning to go to Bodrum in July and stay at WOW Beach club. Is their beach is sandy open area to swim?

I want to know more about the beach because I do not like to swim in the swimming pool so I need to know if the beach at World Of Wonders Beach Club Bodrum is nice, clear and sandy that I can swim in open area.

Also is bodrum good place to visit or Marmaris or Antalya? Which one is the best for me to visit I am planning to stay 8 nights in one of the three places but I do not know which one is the best for me. I am looking for sandy, clear beach to swim and relax and at night I am looking for nice port of cafes, restaurants.

Thanks a lot
