How many days you get from your water tanks is totally a personal thing!
I used to get about a week by myself from 20 gallons of fresh water. Add SWMBO and it drops to less than 3 (killer showers!)
How much water each person uses... Give the kids something closer to a sponge bath using only an inch or so of water in the tub.
Look up "navy shower" and use the lathering valve to minimize water consumption.
Consider disposable tableware to save water too.
All are trade-offs.
Teaching everybody on board about water conservation should be a nice family experience.
