My Mum's stayed at the Sheraton Vistana Villages and Floridays ......... She loved both but preferred Floridays. I've stayed at the Vistana Villages and always try to book top end accommodation, Vistana Villages is superb so I'm absolutely sure Floridays will not disappoint.
Location is fab too .......... IMHO South International Drive is very hard to beat ........ very quiet but still close enough to all the restaurants and ideal for DC, Seaworld, Disney and most importantly the Premium Outlets.
Go for it ............. bet you wont want to stay onsite again.
