I would love every 3 days. I do not need it daily, but I hate vacuuming, washing towels, doing the dishes, and I HATE that I have to pack coffee to have enough for a week.
I am fine without daily, but 65$ an extra 2 times during the trip is a lot. They charge significantly more than it would cost, if it was "guaranteed"/ included.
1 selling point on split staying, is clean new room.
