A short break, expensive-ish hotel…
Our group are:
1 family of 5 (us)
1 family of 4 (dsis)
1 single grandmother
Dsis has booked 3 family rooms - expected occupancy was dsis family in 1 room, us minus 1 dd in another, grandmother and dd in another.
We’ve paid for 1 room plus 50% of the room grandmother and dd are staying in… All fine…
Now the suggestion has been made by dsis that her dd (19) may stay in the room with grandma and dd ‘to help grandma’ (dd is 8 and very independent, dm absolutely does not need help to look after her - they will literally just be going to the room to sleep, activities planned for the whole trip)
AIBU to think that if she wants her dd to sleep in the room we should split the cost of that room 3 ways?
