I have the same situation. I am constantly looking for hunts for my best friend (70), brother (51), myself (62), son (36) and grandson (12).
I agree that Bear are great for this. However, watch out for Idaho -- very steep but we killed 3 bears.
Some don't count turkey as "big game" but I do. We will do one of these group hunts in Nebraska this year, 2nd week of April. NR tags are only $85 and you are allowed 3. Youth are less than $10/tag.
This year I'm looking for an antelope hunt. Blinds over water holes. I'm the only recurve shooter in this group. One shoots only crossbow, the others compounds.
I also know of a tree stand/ground blind elk hunt in colorado that is one of my options for t his group. Three in my group (myself, son, and grandson) can negotiate all-terrain hunts but I don't want to leave my best friend and brother out of hunt plans.
I'd imagine a carbou hunt would fill the bill too but the expense is more than we can do.
