I know that there is often a lively debate about tipping hotel housekeeping staff. I like to tip the housekeepers who work for very little money and overall do a very good job. My question is why don't the hotels do something to make it easier to do? I don't like to carry cash but that is the only way to tip them. Why isn't there an envelope where you can either leave cash or sign to put a tip on your hotel room bill? I think it would greatly increase tips for housekeepers and make their staff much happier.
