As above - we used Super Shuttle from LAX because the price was not that much more expensive than the Airport Bus and they went on demand. We were picked up within 20 minutes of arriving, and altjough the bus then did a lap of the airport until it was full, this didn't take long, and I estimate within 90 minutes of arriving at the Super Shuttle stand we were in our hotel room, despite being the last stop of 4 in Anaheim.
Ps - HoJo Anaheim, you run a great hotel and I make sure everyone here knows about it! We stayed with you December 1-5 2004 and had a great time.
