Last time we were there, we tipped $5 per day, and yes, we did tip everyday, that way, if our Mousekeeper had a day off during our stay, no one got slighted.
There were 2 adults and 1 child in our room, and 2 adults next door. I don't know whether my parents tipped, but the reservations were in my name, so we left the $5 in our room just in case.
Usually, we tip $1 per person per day.
