If you are thinking about taking a trip to the Florida Keys, I would recommend the Amara Cay Resort in Islamorada.   A quick two and a half drive down I-95 or the Florida Turnpike to Florida City where you run into US 1 "aka the Overseas Highway" and enjoy water and island views as you drive to Mile Marker 80. (That's a code in the keys for addresses.)  Actual address is 80001, which means it is 80 miles from the Southernmost Point in Key West (Mile Marker 1).  This was previously a Hampton Inn & Suites that was totally renovated to an upscale 110 room hotel with modern décor on the ocean side.  Very kid friendly with the beach area and playground as well as adult friendly with the Tiki Pool Bar for afternoon lounging and free shuttle service within five miles for your convenience.  We were fortunate to get a Saturday night room over Labor Day Weekend for $162 + tax +++.  We have been going to the Keys for years and prices vary with the best prices in the summer.  It's the allure of the Islands with an easy going lifestyle that makes it worth the trip.  

We rented a boat at Whale Harbor (Mile Marker 83.3) for Saturday afternoon to go snorkeling and ate our lunch at Wahoo's, the restaurant overlooking the marina and ocean.  If you stop there to eat, I would recommend the fish tacos.  There are numerous hotels and marinas in the area to rent jet skis, boats, paddleboards and take dive tours.  

Amara Cay had a very nice restaurant.   However, our favorite place to stop every time we go down to any of the Keys is Lorelei's (Mile Marker 82 on the Bayside).  Outside dining on the bay, with good fish menu, rum drinks and beer.  We had dinner there and the sunset was beautiful.
