If you ever have the chance to visit the Turks and Caicos Islands you have to go! Providenciales (main island where the airport is) is an amazing place. After seeing the beach always named as one of the best in the world we took a trip here... Well we have been back three more times and can't wait to visit again. Island time is in full effect here, no one is rushed, and everyone is laid back. The beaches really are that white, and yes the sand really is that soft. Pro tip: if you are a drinker, bring a bottle or two of wine or you drink of choice with you as alcohol is silly expensive.
If you are staying in the resorts this grocery store is a great place to stock up on water and snacks. They also make excellent sandwiches, but it can take a while the staff fully exhibits the island lifestyle.
