Since whenever most hotels in LV removed the coffee makers, we have carried a one cup coffee maker with us. Even when we carried on! We stuffed it into a backpack or in the over head bag. We are not that cheap--although frugal would qualify--but on some days we just like to get up a little later, hang around the room and have coffee and a cookie for breakfast, then have a larger, late buffet lunch. If we go down stairs to get a Starbucks, we don't have a re-fill, we have to get dressed, and I have to stand in line with the yuppies to be over-charged for coffee.
It would embarrass our kids, so dont tell them---a couple of them already look at us like they think we should be in a "home". I have read on here and other boards that several people do the same, and have even read that some buy a cheap maker when they arrive and just leave it when they head home.
To each his/her own.
