We enjoyed our stay except for a few things. Housekeeping only came to door and usually asked if you wanted clean towels. Room was never really cleaned. No coffee pot or microwave in room (personal preference). Out door furniture very old.

This is a top notch resort! Terrific staff, beautiful accommodations, great restaurant and bars, lovely pools (2) and hot tub, so many sport options, and just a very relaxing but fun place to be. Loved our vacation, we stayed a week. And because it’s in the middle of the Keys, we could get around easily and make day trips to Key West and Key Largo. Marathon also offers a lot.
