Too many good choices out there and we've done most of the common ones (Vegas, New Orleans...) and my group is looking for a different destination. We have a big list of ideas but no one place is the clear winner. Destination and then any extra details you would want to provide would be amazing (hotels, activities...).
If it was just me, I would rent a house, hire in catering, hike and chill but sounds like the group is leaning towards an urban destination (small or big city) in the US or Canada.
