So what are your thoughts on this one.
I live with DH and my 2 children, boy 20, girl 18. DH has daughter,31 married with baby (1). She has never lived with us. DH bought a house in Cornwall before we married. It’s 3 double beds plus a study big enough for single blow up bed or cot. He wanted to be there for Xmas but we settled on Boxing Day with my children staying at home as both have work commitments. Son (and girlfriend) planned to come on 29th and leave 1st. I had come back on 30th for work 31st, pick up my daughter (plus possibly her boyfriend) and be back in time for midnight. We stay until 3rd. My step daughter, husband and baby came over xmas Eve as they chose the day to celebrate with us. Although she has open invitation to Cornwall, She then decided to join us. We of course said yes but said we are short of beds on 31st and explained the plan we had made nearly 2 month previously. She said they would get an Airbnb. 2 days later she asked my daughter to sleep downstairs on a blow up bed. Downstairs is open plan with no doors or door on staircase. My daughter has given up her bed since she was 5 every time my step daughter stayed either at my house or husbands in Cornwall so my daughter said no. My step daughter phoned her dad, screaming that it’s not right and she should have a bed as she has a baby (who would be sleeping in the study) and her husband is 6f1. I argued it was only for one night and it was unfair for my daughter to be woken up during the night and very early in morning as the baby would be up early and she would need the kitchen. The next day my daughter confirmed her boyfriend was coming too, but step daughter then refused to come if she didn’t have a bed. DH has said she could have the bed and my daughter had to sleep downstairs as her boyfriend wasn’t really welcome anyway and certainly not if it meant his daughter wouldn’t come. I had suggested they go to the nearby (20mins) premier inn leaving the baby with us (he has stayed with us overnight before) or they come on 1st instead. Both were refused. I maintained we had already made plans and my step daughter only decided a couple of days ago so she should have the blow up bed. But husband maintains his daughter should have it because she is older and has a baby. So who should be on the blow up bed?
For further context, I came home and my children decided to stay with me and no go. Husband is staying in Cornwall and his daughter is still visiting.
