On my 5/18/02 trip, National had the best rate with a Disney Club discount. My husband and I just flagged the first cab we saw in the parking lot across from the terminal. It was about a 10-15 minute ride to National and they did deduct $11 from our total as reimbursement for the cab. I want to say we paid about $60 for a minivan for a 1 day rental.
