Honeymooning in Turks and Caicos

My FH and I are so excited about our honeymoon in T&C but I am overwhelmed with all of the choices. I have narrowed down to Grace Bay in Providenciales but then I go crazy. There are so many amazing hotels. Has anyone been? We are looking for great beach, romatic setting and alone time (but not totally secluded). We don't want to rent a car and would love other resorts to be within walking distance so we can be out and about a little.

Any advice would be amazing. thanks.
