I'm going to be staying at Shades of Green the first week of April 2007, I know they provide bus service to the different parks, but would it be worthwhile for us to rent a car instead to be sure we got to the parks early each morning? Also does the bus service continue late at night for the 3 hours after parks close to take us back to Shades of Green? We're taking along a 14 month old so we're debating on renting a car.
