Anything could be outside your hotel's doors. Maybe a beach, a forest, or even a race track roaring to life. That's the opportunity offered by Adventure Calls RV, a company specializing in RVs and travel trailers that put all the amenities of a hotel on wheels. Their vehicles house multiple bedrooms, showers, and even pop-out awnings. Take the Poppy unit, for example. It can accommodate more than nine people and comes equipped with a full interior kitchen and outdoor camp kitchen, complete with gas grills so musicians can warm up their instruments before the big festival.
