We don't travel much, usually once or twice a year so it's not even a line item in the budget. While I share some of the expressed feelings about tipping there is also nothing to be gained by me penalizing some low-wage worker who is, at least, working. So we tip the hotel maid $5/day. That will probably go up a few bucks the next time we stay in a hotel since both my pension and SS are COLA'd.
