can you accommodate 72 people in your cabins or bunk houses and how much

This is Google maps, not Yosemite National Park. You would need to make any reservations almost a year in advance, as this is a popular place to visit.

Yes 6 people is Max for the cabins

Each housekeeping unit can accommodate 6, so you will need 12 units, though 6 people per unit is pretty tight. Plus I don't think you will get 12 units at once unless you reserve a year in advance. Good luck.

how much for 1 cabin ( for 6)
