I typically don't tip in hotels since I keep my room organized and clean and I often skip room make up service altogether. Some hotels now offer an incentive for skipping: either a voucher or some charity donation for something "environmental". Most rooms have plenty of towels & supplies to restocking everything each day seems like a waste.
So unless there is significant clean up work, I'd keep it a $2/day for the days of actual service.
