I highly recommend the Residence Inn. It is within a few block walk from the front gate (I was able to do it carrying two kids and I'm not in great shape). It has a free, though relatively low quality breakfast. However, it was perfect for fueling up 6 excited 3-6 year olds prior to entering the park. Also, it is right next to the GardenWalk shopping center, which provided nice alternative dining options to the Park.

I used upgrade certs (a total of an extra 10k points/night) to upgrade to the "penthouse" suites. These are two floor, 4 bedroom suites. We were able to fit two families (shhh!!) in the rooms with plenty of room to spare. They also have free barbecue cookouts a few nights a week.

We have used this property 3-4 times for Disneyland and always enjoyed it.
