Hmm, I don't remember one where you check-in, although they did have one by Pioneer Hall at one point, just southeast of the Hoop Dee Doo.
The camper would change at times, I guess based on whomever was sponsoring it. You could walk into the camper, check out the inside, was a nice little break when you were walking that way.
It hasn't been there for a couple years now I believe, not sure what happened, probably didn't result in very many sales I would believe.
