Close what you will not vote on the road
The drama of a trip with friends is almost never the destination. It is not knowing who pays, who chooses, or what time you head out. Agree on budget, pace, and one person who confirms bookings before you buy the ticket. The rest can be voted once you are there.
The budget has to be a number, not a feeling. “More or less” leaves someone out without saying so. If the number does not work for the whole group, change the trip, not the hope that it will sort itself out on site.
