That's nice. I never thought to give more the first day. They are preparing the room for us, and giving new bedding. It is more backbreaking. I will tip more the first day in the future.
I tip heavy the first day because I have a few idiosyncratic requests that I make of the housekeeping and I want the maid to understand that I appreciate the extra care I am asking her to take.
Four things in particular:
That I have some specialized equipment in the room but it is not fragile and can be moved out of the way if needed like she would any piece of furniture. I say this because in the past, people have seen a small stack of cases or a PC running on a wheeled cart and out of nervousness over possibly breaking something they just left that side of the room alone.
That the room is, at all times, under electronic surveillance. I don't have cameras in the room to catch housekeeping doing something naughty, I have them to prevent it. Actually, I have them because I have an obsessive need to know who has been inside 'my space'.
That I have a sleep disorder that causes me to, sometimes, still be in the room when she arrives and at times I may appear awake but be uncommunicative. I want housekeeping to know that I'm not dead or dying, that I will be fully clothed and decent, and she is welcome to clean the room or not based on her own preferences. On the occasions where this has actually happened I slip an extra $10-20 in the mousekeeping envelope.
That I would appreciate it, if at all possible, if the same Mousekeeper managed my room every day. Some of this request is a practical matter of not wanting to repeat this whole spiel every day to a new person. Some of it is a crutch to support a very specific anxiety issue of mine. I coordinate this request with hotel management and have been accommodated pretty well all things considered.
So, like I said, I have some special requests and I tip a bit heavy the first day because I'm asking the maid to work outside her normal parameters.
