Located at MM 49.8, the Sea Dell Motel is in the center of Marathon Key and the “Heart of the Florida Keys.” Our spotlessly clean rooms have refrigerators, microwaves, and coffeemakers. A washer and dryer are also available on the premises for your use. We maintain the temperature of our beautiful freshwater pool, and we offer barbecue and picnic areas to enjoy with your family and friends. The Sea Dell is only 1½ away from Sombrero Beach, one of the most spectacular beaches to be found in the Keys. Each of our rooms is smoke-free and we invite you to connect to our free ultra-fast wireless internet – rated fastest in all of the Keys by hotelwifitest.com! Need to charge your electric car – we have an outlet for you. Our ADA room and our facility were remodeled in 2014 to be compliant with the latest 2019 ADA regulations from the State and Federal Government, including van-accessible parking adjacent to the room.

The Sea Dell Motel is located in an ideal area very close to many attractions, restaurants, shopping, scuba diving, snorkeling, fishing charters, and more. We are just down the road from the Dolphin Research Center where you can swim with the dolphins and Crane Point Hammock, a 64 acre protected area of historic sites, nature trails and museums. Fine restaurants, shopping, fast food, grocery stores, live theater, and movies are all within walking distance. Our location right in the middle of the fantastic Florida Keys make the Sea Dell Motel a perfect vacation destination.
