The Park Vue Inn, right across the street from Disneyland has a 2rm, 3 queen bed suite. I have that reserved for our trip in December. 1 room has 2 queen beds and the other room has 1 queen bed. The motel gets pretty good reviews on Trip Advisor.
Dangermouse is right; our biggest room is our Queen Suite room. It has a room with 2 queen beds connected to another room that has a full size pull-out couch and a kitchenette. The max capacity for this room is 6 guests, if you wanted a bed for the 6th person, we could get a rollaway bed sent up to the room for $15 a night plus tax. It is a very nice room that can accommodate a larger amount of people. Hopefully this is something you would like to look into!
We always stay at the Desert Inn and Suites right across from the crosswalk. It has a room with 4 (!) queen beds and 2.... yes 2.... bathrooms. It's really great!
