If local I’ll often go to a meet with only ID, one credit card, and cash in pocket for fee, only....rest stays locked in car. Even if I’m checked into a hotel.
Traveling always use room safe, front desk safe (great choice though not as available as used to be), hide stuff in room or in rental car.
I’ve always figured if I get forced out to parking lot I can make enough of a vocal stink to get attention, use car panic alarm Etc.
