how many people can float at the same time? I was thinking ..as a gift for my daughters?

3 tanks. 1 pod 1 larger tank w doors 1 tank large without doors You can book ahead a massage one at a time as well. Also they do light therapy I believe.

3 tanks, 1 person in each, they do have a very nice sitting area that you could take turns

They have 3 tanks, but only one person per tank.
