We tend to our own bags since we drive...and it is just easier for us to go ahead and do it.
I do tip mousekeeping $1 per person per day...and I pick up after my family alot, so aside from a quick drop off of towels, & making the beds, alot of times there is not much for the maid to even worry about. I know there are envelopes you can print out on here for mousekeeping although I have never even looked for them. I just sit down with the kids prior to the trip and we make one out for each night we will be gone. I know alot of people say that you don't get any better service, but we came back to a new and creative towel animal each night.
