I'll try to be as to the point as possible.
Me, dp , ds1 (2 yrs old) and ds2 (8 months old) are going on holiday on Saturday for a week, paid for by and going with my parents. This has been arranged for just under a year.
Dps family live 20 minutes away from where we are staying which is why the location was chosen.
Due to lack of space at dps family's, he and ds1 are going to stay the night Sunday and Monday to spend quality time. He wanted to go on Saturday but I thought travelling and unpacking and then going off again somewhere else would be a bit much for us all and wanted to settle in first....considering we aren't allowed in the holiday house until earliest 3pm. The journey will be 4 hours not including travel breaks.
Dp told me last night his grandparents will all be there on the Saturday and they are leaving on Sunday so he needs to go on Saturday. Asked him if they could come to us that evening as it's only 20 minutes away but dps family have said it's too much hassle for them all to come to us.
MIL wants us all to go on Saturday and for dp to stay Saturday and Sunday with ds1.
Feel like I can't say no now. Even though dp had already told MIL I didn't want to do that.
It was a holiday for us and now feels like it's being controlled by dps family even though my family have kindly paid for it all.
AIBU to stick to my guns and say no to Saturday or should I just go and accept I'm being dramatic and unreasonable?
