Here in Oz, most caravan parks will have a camp kitchen (a kitchen anyone staying in the park can use) along with general purpose BBQ's. They also usually have either caravans or cabins you can stay in. Do U.S. RV parks have cabins (or on-site vans) and camp kitchens?
What I'm trying to determine is, If touring by car (as oposed to a RV), are there any options other than Motels. This is for a family of 4 (2A 2C). It's usually much harder to get a motel room suitable for a family rather than a couple.
