For the ultimate getaway try Little Palm Island. It is tucked away offshore on Little Torch Key at the end of the Florida Keys. You'll reach the island with a quick boat trip aboard the Truman, it's about 3 miles off the mainland but you will feel a world away.
The resort is spectacular. Each room has romantic touches like netting around the bed and ocean view verandas. Some rooms have outdoor private showers as well. Just a note- there are no televisions or phones in the room so plan to spend plenty of time with other entertainment!
During the day you can wander the island and lay in the hammocks among the trees, or lounge by the ocean or pool. If you want adventure you can take a snorkeling tour to the nearby reef or you can take the Truman back to the mainland to site see. In the evening enjoy dinner at the Dining Room and eat outside by the ocean with the warm tropical breezes. The resort give you the option of purchasing a meal plan so that all your meals are included.
For the ultimate in romance you can pay extra and have specials touches added to your room, such as turn down service with rose petals, candles, massage oils, etc.
With all of this I guarantee you will never want to leave this island paradise!
