We are trying to plan a trip xmas 2007. My dad is insisting that staying onsite saves time driving in because you can take a bus. I think if you have to wait for the bus, possibly drive to another hotel, and then still drive into the park, that it is just the same as driving 15 minutes from off site. We really cant afford onsite, so we would have to stay at all stars. What are your experiences with the busses at a busy time of year?
