Suggestions of where to stay?

Going to Orlando...wife and I want to see Animal Kingdom (1 day) and revisit Epcot (2 days?). Spend 6 nights near the end of April. Have Hilton points (200,000) and Marriott (175,000). Silver with both. Long lost higher status.
Will likely rent a car (portion of the time?) and take the trams to the parks.

Trip to be later portion of April 2007. We will fill in the time gaps with other activities later, but all will be a modest commute from hotel.

Thank you.
