We are going on our 1st DVC trip next week. We are spending 6 wonderful days at Saratoga Springs. I know mousekeeping does not come in everyday, but I believe on the 4th day they do, correct? Previously when we've gone we've always left a tip for our mousekeeper in our hotel room daily. Do we do the same for our villa too, & if so, how much?? There are 7 of us staying in a 8 person villa.
