AIBU to take my children away without OH?

[pinkgoo]

My OH is having to travel away for work over half term, so I will be left to juggle child care and work on my own. I want to take the kids away for a couple of nights in a caravan to give them something nice to do as
I will be working the rest of the week. OH has said I am selfish and shouldn't be doing this without him.
AIBU ?

YANBU. We had new heating and a new kitchen put in last year. I took the kids to Centre Parcs for a week and left DH at home to oversee everything. We had a ball. DH, not so much
