Campers can certainly be fun even without the bike aspect. But I have to wonder, what 'layout' configurations could possibly make any difference with a bike? Folks get 'toy haulers' for hauling vehicles but you could stash a regular bicycle(s) just about anywhere in one or even in the back of your truck. Not sure what trailer layout really has to do with it.

On the camper vs hotel debate... depends what hotel and where (often time the cheapest one around could be well over $100 a night) plus campers give you a lot more freedom (fully self contained units can be operated from anywhere you can stay). It's nice to have a fully stocked kitchen with you, your own bed and sheets, no bed bugs, no people making racket on the other side of the wall, etc.
