My DH and I go away with my single brother now and again - we try and get a family room, and split the cost in three.
A couple of times, when he has made the booking, I have paid what he has said is our share... and then realised afterwards that he had simply added the cost of the single room and the double room together, and split the cost in 3. So we ended up paying more for our double room = subsidizing his room.
We have an upcoming weekend away and he will have a twin room and us a double... and he's said 'let's just split it in 3'... and I really do not think it's fair. Have said we need a family room, or he pays (in full) for his own room.
AIBU?
He thinks I am... 'poor me, always paying so much as a single person...' The usual story. We cannot help it that he is single.
