Hotel rooms -how outdoor you divide the cost?

Pay for your own room, single or double.

You each pay for your own room. Why would you not? If I was going with my adult children, well I would probably pay for them myself. Just a parent thing.

Each pay for their own room.

I always find that tricky.
We tend to, the single person pay half the "extra" cost, and the others pay the remainder of it[assuming they are happy about doing that].

Just a thought , but have you considered taking a house over instead of a hotel, if you plan to be together for more than a day or two? That way you share the cost between all the people staying there so then if you are a couple you will pay for 2 people and a single will only pay 1 amount. Then you have the choice to agree previously whether you will pay someone to come in and cook for you or do self catering in any way that suits you. I dont sleep well and prefer this sort of thing as I can get up very quietly but if I am longing for something to eat at 5.30am and you want to sleep in until 10am doing our own breakfast tends to work out much better, and also covers things like anyone with children who want to eat at their usual time. So breakfast is easy to cater for with cereals, coffee tea, eggs and bacon and toast available for everyone. Then you do your own thing or get a take away sent in for everyone and again can have a kitty and so some can have pizza and some chinese or whatever but you have that flexibility to do what you like. as you are all at the same party you can stay up all night if you want with no other guests to disturb.
If that doesnt appeal then I would suggest that you state beforehand that everyone can pay their own bills for the rooms and then everyone is treated equally, but also on the quiet there is no reason why you might speak to someone and say you want to pay all or some of it for their birthday/christmas present as you didnt have chance to get them something. That way saves face, for everyone, doesnt put anyone else into a position where they feel obliged to do something that they might not want to .

Each pay for their own room, as a single traveller a double for single use is double the price, however if it were youngsters with not much money I would pay for theirs.

Pay your own by far the fairest and best way
Whatever my finances I d always want to pay for what I had

I think it depends on the structure of the family and who is in the single rooms. It also depends on the relative financial circumstances of those involved, and the purpose of the stay.

If the single people are young, or much older than the couples, and have less money, I would split the bill in a way that made it cheaper for them. If everyone is the same generation and of similar means, then everyone should sort out their own bill.

Also, if the trip is optional and for fun, so people can choose not to go if they will be stretched by doing so, that’s different from something like a wedding or funeral that is harder to get out of. In the latter circumstances it would be a kind gesture to make the bills equal per person, rather than half price for members of couples.

I don’t think it is a ‘one size fits all’ situation where families are concerned.

I agree Babs .

I would suggest everyone pays their own way. Either way could cause someone to complain but I think just getting everyone to pay for their own room is probs the line of least resistance.

Sorry about typo in title
