Am I being taken for a fool by my family over my mum?

For years, it has fallen to me and my sister to take my mother on holiday. Now, she has a big birthday coming up and wants me to arrange a trip abroad. I have three other siblings, who have never taken her on holiday, so to prod them into action I spoke with one of my brothers, who expressed disbelief at my mum's request and told me I was a fool for going along with it.

I can’t decide if he’s being mean (our father died a few years ago and she doesn’t have friends to go with) or if I am the fool in the family. I have young kids and a tight budget, but our holiday has to be arranged to suit “Granny”, so it ends up being a nicer hotel than we would normally go for and a less adventurous, more expensive trip than my siblings take with their kids.

A little part of me is wondering if my mum is playing me for a softie and not making demands on my siblings because she knows I'll cave.

Related to all this, there’s a wild inequality to the inheritance that’s being left, with the lion’s share going to my eldest brother. Mum has also helped out with his children over the years, but always refused to look after mine, even for an evening.
