We will be first time visitors to Orlando, staying for one week next April. We have a 2-Bd/2-Ba Marriott timeshare elsewhere we are exchanging but are uncertain which Marriott property will give us the best bag for our timeshare buck. Any suggestions? We are traveling with a 17 and 15 year old. We are veterans at Disneyland, but are clueless with the wide range of options for the Orlando area. Someone suggested the Marriott Grande Vista but we are open to other ideas. Thank you!
