Lime Tree Bay Resort

Lime Tree Bay Resort

8/10 Good
"We stayed at the Lime Tree Bay Resort from August 20-24, 2026. Positives - The main pool was nice. Clean and never crowded. Our room view at sunset was beautiful. The elevator worked properly and the property was clean. We are a retired couple and have never left a negative review. However there are a few things to report. Site is quite isolated. It is 12 miles in one direction and 20 miles in the other to find restaurants and shopping. There is a bar and grill on site so we decided to try and eat there two different times. Both times there was no one there to wait on us. The worst part was regarding the parking spot for our room - 153B. Impossible for parking. We hit a yellow pole while trying to park in our assigned spot. The office did not seem concerned when we reported it. They kept moving us around to empty slots. Finally the assistant manager had us park in the manager’s spot since the manager was gone for a few days. No one asked us about our car damage. We did take photos of our car and the parking spot. The parking was made more difficult because a large vehicle (Yukon) was parked next to us. Our room was not cleaned one day and another day we did not receive clean beach towels. I made many trips to the office which should not have happened. We will not stay at this resort again."
