We are staying at a DW hotel for the majority of our December 2010 trip. My oldest son really wants to go to universal, so I am thinking of stayng at a on-site hotel Sat. night and going to Universal for one day--Sat, Dec. 11th. We will then fly home on Sunday...how do we get to the airport? Disney offers a free Magical Express service, do the Universal hotels offer something similar? We will not have our own car on this trip. Thanks!
