For lghr and anyone else that needs the info: Here's a link to the Town Car Service my cousin just used in October. http://www.wdwtowncar.com/sanford.htm
It says that it's $150 from Orlando airport to Disney resorts (which I think is pretty affordable). Here's what my cousin had to say (couldn't say enough good): I know there are ones that are cheaper but these guys really were great and very professional, our driver was very knowledgeable about the area and made us feel very comfortable instead of having those crazy taxi-like drivers who swerve in and out of traffic...Any just my 2 cents. Of course I don't have anything to compare.
