Ya that is the big unknown for me, I know at the hospital im located now, we have to park at a lot not at the hospital and take golf cart transport to the hospital, but its a huge lot and we have had a few travel nurses boondock in the back corner of that aux lot. We had a nurse who lived in a Tesla Model X, slept in the back of the car with the rear seats removed and mattress installed, would sleep at hospital parking lot for his 2-3 days in a row, then leave on his days off and camp out somewhere else like a state park or what not to reduce his lodging expense. We also had someone in a Mercedez sprinter van try to spend the entire 13 weeks in the back corner of the aux lot, but she was eventually kicked out, because she was hanging out cooking and such in the parking lot and drinking beer on her days off instead of leaving the hospital. We even had a nurse with one of those big dually Mega Cab dodges camp out in the parking lot. She has an RV and parks it further from the hospital to save on rates, then she would schedule her days 2-3 in a row, shower in the OR changing room and sleep in the back seat of the truck for her 2-3 days, then go to her RV on her days off, told me often she would find RV parks 30-45mins away would be half the rates of parks near the hospital. An example she said the RV park down the street from my hospital is $1050/month right now, she parked at a resort 45 mins away for $440/month .
