When staying less than 8 nights we will call housekeeping and change our TT day .. for 6 nights, we would have them come on day 3, so hanging up towels and reusing isn't a problem.
We just stayed 8 nights at AKV and asked for our full cleaning on day 4 and our TT on day 6 .. no problem with either request. I couldn't see waiting until day 8 for a full cleaning, when we were leaving the next day!
We also toss towels in the washer if we begin to run low before TT service.
One of the pluses of the villas with an extra bathroom ... our two bedroom at Kidani had 12 bath towels ... 4 in each bathroom! With 6 of us in the unit, and changing our full cleaning and TT days, we never had to wash towels!
