I spent about 100 or more nights in a motel with my bike parked out side just this year alone.
Motels are the last place you need to worry about now days. I can not remember the last time I saw one with out some kind of security cameras.
And They never have a problem with you parking your bike up front were there are eyes on it all the time.
Some even have special parking spots for them .
If you want bike were you can see it from the room talk to them about that when you make reservations. They will not think your crazy.
Wow! Even at $50/night, that's a major travel expense. Do you have a way to deduct that from something other than your annual income?
