I don't really expect int to be an issue, the people I'm going with are all very easy going and more likely to object if they feel they haven't paid their share than because they think they've paid too much, but on this occasion I'm the organiser and also (possibly) might end up with the best deal, so want to make sure it's reasonable.
It's a short trip to do an event. 5 of us, one married couple, 2 men and me. I've booked an apartment with 3 bedrooms, a double, and two twin rooms.
So married couple have the double, two men one of the twins (they're happy to share) and I'll end up with a twin to myself. Not intentional, just how the most suitable accomodation worked out.
So, do we divide the cost by 5 people, or 3 rooms?
