Trying to decide on which Orlando resort. We will go to Disney maybe 2 days. Plan to visit Sea World and some other local attractions. Bringing my daughter and 3 year old granddaughter. I like the idea of access to Marriott World center if we stay at one of the Marriott Palms. Not sure how their kids activities are. Grande Vista seems to have many kids activities. Also looking at Sheraton Vistana and Sheraton Villages. Any help would be appreciated.
