OT- Disneyland Very OT
Another REALLY budget place is the Alpine Inn on Katella . . . very old but clean . . . my kids grew up thinking that was the only place to stay in Anaheim . . . and I still check there if I'm spending the night up there. There is a gate to walk into Disneyland not far down the street.
Also - get one of those hotel discount books . . . I think all the Denny's have them by their front door . . . you can get coupons there for decent discounts sometimes.
