I haven't stayed at many hotels/motels in my life even though I was a assistant front desk manager at a Holiday Inn back in my 20's. Pretty cool job actually until people start b****in about stupid crap. We had a cartoon hanging in the back that read, "What if we send up a fruit basket, a bottle of champagne and have the manager shot? Would that be satisfactory?"
Anyhow a few months ago the ol' lady ticked me off so I went to stay at a motel and there was an envelope in the room for leaving a tip to the maids. Never seen that before but I put 5 bucks in it. It said you could leave it in the room or drop it off at the front desk when you check out.
