I booked 9 nights at Sheraton Vistana Resort mar 28- apr 5. I was given the AAA South rate. My son had a severe knee injury in his last Basketball game of the season. If all goes well he will just be getting his leg brace off at the end of march. I changed our reservations so we will arrive the day before easter. I asked for the AAA rate and it was much higher then what I originally booked. I figured it would be, because of easter. I asked if it was the AAA south rate and the girl checked and Quoted me a rate that was $50 per night cheaper! My AAA card does not say a region on it. Just curious if anyone else has experienced this, and what the difference is?
