3 weeks ago, i visited this resort with 2 friends ( we are all in our 60's, so no, we did not trash our room)was overcharged $50. on hotel stay. Even though I had my reservation confirmation AND when they listened to the recorded message, it also confirmed the price I had on my reservation. They said they would correct it, but have not.
