Find Dog-Friendly Hotels in Grassy Key, FL

"I would have given Coconut Cay a 5 star review again this year, but we had a terrible check in experience! We booked a King Island Room online in October 2025 for our stay this March 2026. We paid with credit card in full and since it was our second year booking we were expecting a very bright nice room with a view, just as shown in the photos on Expedia!! Instead, when we arrived, we were told that our room would be in the front of the hotel, right next to the office. A very dark room with no window!! The staff person said that was our only choice unless we paid another $700 to upgrade!! We were shocked and complained, but to no avail. Finally my sister and her husband spoke to the staff on our behalf and the manager was phoned and agreed to give us the room we had paid for IF we paid another $364!! We did pay the crazy upcharge fee and enjoyed our stay, but we paid more than my sister did and she had a suite with kitchen area! BEWARE WHEN YOU BOOK THIS HOTEL ON EXPEDIA!! We love Marathon Key, but not sure we will stay at Coconut Cay and get robbed again."
