Find 3 Star Hotels in Grassy Key, FL from $214

"Pool was great! Marlin room was great location and very nice. Enjoyed it a lot!"

"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."

"Excellent all"

"This resort is a solid 3 star. Check-in is definitely 4 pm or later. No rooms were ready any earlier. Rooms were updated, except for the TV's which were small and dated. (this is my husbands complaint) Clean, however no daily room cleaning unless you ask. I did request our sheets to be changed but the bed was only made, not changed. The bedroom air conditioner blows directly on the right side of the bed, so this took some adjusting in the middle of the night, thus the request for clean sheets. Breakfast was tasty but limited, scrambled eggs or hard boiled, bacon and waffles. Bread, English muffins. Coffee, juice and whole fruit available. I wish there had been some muffins or danish for those with a morning sweet tooth. We never ordered lunch but I did see quite large portions served, mostly leaning Greek. All look good. The pool was nice, typical lounge grab in the mornings. Nice, large new umbrellas. Live music some afternoons. Everyone in the pool made for some murky water, but everyone seemed happy. Lots of boat talk. Overall a positive stay for us"

"Chair in front the desk look like someone went to the bathroom in it and was NEVER cleaned during our week long stay. Plus 20.00 a day to park and 35.00 a day resort fee was nothing but a joke. We won't be back. "
