How would you share the cost?

[G5000]

Mum and my family (DH, 2 small kids) have booked a holiday. Mum offered that she can share with kids, so we got a nice big suite (separate bedroom for mum and kids) in a bit nicer hotel than she would have normally booked. Shared the costs 75-25%. Booking is not refundable or changeable.

Now sister is sending my (teenage) niece with us. No problem, she's lovely and great company. Of course, no room for her so we agreed to book an additional room. Sister does not want that niece is there alone, and of course makes more sense that mum then shares with niece.

How would you share the costs? Option A - mum already paid her share; we only needed room 2 as niece is coming, so sister pays the full cost. Option B - mum is using the room as well, so they go 50-50 and we pay 100% of room 1.
Option C?

So just to be clear, there are currently no disagreements or disputes and I'm sure we manage to work it out, was just curious what other people would consider fair. If relevant, sister and I are better off than mum, but she can afford the 50-50.

Option A.

Its your sister who has changed the dynamics so your mum should not be burdened with any extra expense, simply due to a change which she - apparently- has had no input in.

Option A

I would be pretty miffed that I now had it share with dc tbh!
Dsis gets the best holiday!
Home alone!!
Dsis needs to pay but I bet she won't...

Yup option A!

Option A seems fairest all round x

Option A, the only reason you need extra room is because of your niece so sister pays the cost.

I would suggest sister pays 75% of the room rate - she's getting childcare too and whose going to pay for the other costs

windy no we will still keep the suite and DC will have their own room. Original plan was for all 5 of us to share, me and DH in one bedroom and DC and mum in other.

stuck yes I expect I will pay for the extra cost like meals and trips for niece. It's not a problem really, as we can afford it and she's great with DC and we like to spend time with her.

Or you could let your mum have room to herself and keep all DC together?
But full room rate still falls on your sister.

A

Interesting, I thought most people would go for B.
Red I wouldn't say she didn't have input, we simply didn't discuss the costs. As said, ours was already booked and not refundable, so when niece decided to join us, we didn't have other options but to get the extra room.

Personally I'd say option A. Your Mum was happy to share the room with your DC and has paid her way fairly. Now niece is coming and wants her gran to say with her, this requires another room. Her Mum should pay not gran.

I'd speak to Gran and ask what she thinks is best.

I'd leave it to your sister and the gran to sort out how the cost will be divided for the new room. The cost of your children's room was already agreed and settled.

A.

Your sister changed the dynamics, she should pay any associated costs.

I think B. If you are paying the full cost of the suite then you can “ reinbuse” your mum and put that towards the second room. Sister pays the difference.

Why not tell us the ££££ ?

How much difference will each option cost? And whom?

You sister should pay for the room, for your mother to stay in, DN should share with DD and give your mum a rest.

Sister should also pay her share of food and treats plus extra for you all taking her

Option A. I don't even know why people are questioning this. Why should you pay more because your sister wants to get rid of her kid for a week?

Do you feel as though you were forced into taking your niece?

I'd leave it for your Mum and Sis to sort out.

Ginger not really. She was always welcome, as said, lovely girl and we enjoy having her around.

I really haven't made my own mind up about the fairness of this. I think mostly as mum would have wanted to book something cheaper if she wasn't sharing with us, so feels kind of unfair to ask her to pay half of the additional room. I think I will propose as nothing suggested - mum's share will go from our room to the other, sister pays difference.

For me it depends how much the actual monetary value is - £200 is a lot less than say £750 and that would base it on whether i just swollow the cost iyswim

But probably option a

Option C

Given your sister insisted your niece go she should be covering the food and activities not you.

SOCKS the new room is about 900.

IceCream in principle yes, but we don't normally do this in our family. But similarly I would not expect to pay for food and activities if sis was taking care of my kids, so it works out.

I think you pay 100% of room 1 as that is what you are now using.
Your mum doesn't pay any more than she has already paid. So your sis pays the cost of second room LESS what your mum has already paid.
