Just across Harbor Boulevard from the Disneyland Resort is a quaint little hotel/motel mix with a lot of charm for not too bad of a price. It may not be the most affordable option but this has proven to be one of our more preferred Good Neighbor Hotels.
The Holiday Inn - Anaheim Resort Area is a very nice hotel. I usually have good luck with the Holiday Inn. I got this hotel on a good deal from Priceline which was helpful. It is a little far to Disneyland, but it is a nice place to stay on a budget.
