Think about basing around some activity, for example golf, fishing, hunting, horse trekking- then just select the venue- most of the stags of our friends are done this way- they then all descend either on the Friday night or Saturday morning, depending on family or work commitments ( or indeed on alcohol intake capacity), have a few beers on the Friday night, do whatever activity Sat afternoon, dinner that night, more beers, and home after hungover breakfast on Sunday.
