Walkerville Hotel

The Walkerville Hotel is a hotel and convention center located in Walkerville. It appeared in the episode "Goes Cellular" where Arnold (whose skin became orange from his addiction to Sea Wheedies) is selected to win Great Rock Admirers' National Institute of Tectonics Experts' Rocky Award from GRANITE and the class (except for him and Phoebe) take a field trip inside his body to locate the Beta-Carotene and change his skin back to normal.

In When the Cold Breeze Blows Away, it is where the How I Can Help Make the World Great's Walkervillian guests can located to rest.
