Hello, I am planning a three tank centre and I feel like I am just guessing at the number of towels to budget for. How many 'floats worth' of towels/robes do you have on-hand? How often do you run your laundry machines? How many guests actually use the robes? I assume that each float requires one bath towel, one hand towel, one face cloth, and perhaps one bath mat... in addition to several clean face cloth size towels at all times for the WC. Some real- world insight would be helpful here, thanks!
