There is always the idea to take the bikes in the hotel room with you. (Yes we've done this actually). Anytime we take the bikes somewhere we take the Ford Ranger (small pick up) that we have a bike rack that attaches to the hitch. We just don't take the carbon road bikes on that since they have to hang by the frame. Typically it's the mountain bikes we're traveling with. But we do take them in the hotel room with us. When we took them to the beach (outer banks) we actually had them locked on an upper balcony under the roof and where you could not see them from the street instead of bringing them inside. Oh and they were locked right next to the door on that lvl.
