To the east of WDW on the Atlantic side is Coco Beach or Daytona Beach, so sorry, no clear blue water. To the west on the Gulf side is Clearwater Beach and in Sarasota, my favorite, Seista Key Beach which has the purest white sand anywhere, feels just like talcom powder. All beaches can be reached in approx 2 hours if traffic allows. Any hotel that has trip brochures will have info on directions....it is mostly I-4 both ways.
