Renting a car at the World-Discounts?

[hrslvr142]

I have done Disney many times, renting a car at MCO but my guy does not like doing that...so since life is about comprise have a couple of questions. We are going in December and only staying at the World 3 nights and then off to other adventures the rest of the week. I saw a thread recently where people were getting great rates from Hotwire but I believe those were all rentals at MCO. I can't figure out how to get Hotwire to give me a rate at/near MCO. Could anyone give me any tips? Thanks so much.
