Marathon Dolphin Research Center Hotels

"Grassy Flats is an amazingly beautiful property. From one end to the other it's like a little slice of paradise for sure. We stayed in the wreckers building. The room was fantastic, clean and very comfortable. The pool was warm and hot tub was delightful. Restraunts were closed when we were there so we ate at the market. Fish tacos were pretty basic. Overall an excellent stay."

"Great property. Our room was extremely cold so we turned the air off and used the ceiling fan."

"It is so hard to know what the vibe of the place is going to be by the photos and other reviews online. I was thankful I picked the right place for my family to vacation at. Rainbow Bend was laid back, small, quiet, private, and low key. I think they only have like 22 rooms.This was our first time to the Florida Keys and I was so happy to stay right in the middle of the Keys just outside of Marathon! We enjoyed the Rainbow Bend property very much. We could have breakfast under palm trees with an ocean view, pretty fantastic if you ask me. Heavyn and Joy were great resort hosts! Our beach view lodging had a patio area, kitchen, dining area, pull out sofa, master bedroom, and a very nice bathroom. It was just perfect! Thank you for a relaxing vacation! "

"The property was excellent and the view was amazing! We had a nice relaxing week with plenty of fishing, swimming in the pool and admiring the manatee and fish off of the pier!"

"Beautiful house with plenty of room for all guests. "

"Room was clean, bed was comfortable. Not a great location for beaches/attractions but we were just passing through so it worked out."

"House is in a great location. House was clean, Beds were comfortable. Kitchen is starting to show some wear and tear. Very low water pressure in the showers. Outdoor furniture needs fixed, lots of chairs are broken. Pool was great. House needs and outdoor kitchen area. Beach/water is not useable as mentioned in the description however there is a smell by the water at low tide. House offers beautiful sunrise pictures. Overall we had a great vacation but like the gulf side much better."

"We did not go swimming but enjoyed facilities. Nice grounds and friendly neighbors"

"This property was everything we had hoped for. Spacious social areas, heated pool, and wonderful pier that my family fished from every day catching many mangrove snapper. I am sure we will be returning next Spring. I highly recommend this property. The icing on our vacation was seeing sea turtles and a manatee from the pier. "
