I'm in a group of 7 so we're looking @ 1 - 2 canisters, depending on size.
I'm thinking you are going to need at least 3 cans for 7 people. I can get about 6 days of food in one, if I condense and repackage everything. If you are planning on using prepackaged freeze dried Mountain House whatevers, you will not get by with one or two canisters...using the standard rental canisters, Garcia weekenders.
