If you're looking for cheap then you could try the Super 8 on Katella which goes for about $50-$60/night. It's certainly nothing fancy but it was a place to sleep. We walked to and from the park when we stayed there with no problem but it's not as close as some of the hotels. I think it took us about 15 minutes to walk to the security check. They have free parking and free breakfast (cereal, muffins, juice). It's also right next to GardenWalk.
