Hello Does anyone have any reviews or opinions on the Hilton Grand Vacations Club at Seaworld? We would be having a one bed unit for two adults. We are trying to decide between this and the Sheraton Vistana - which there is tons of great info. about on the boards. It will be a bonus week rental through RCI ($525 for a week inc tax & fees) so I don't expect we would get one of the 'better/newer' units in either case?? Thanks for any help and opinions.
