You are all just wonderful, thank you for the support, wise words and occasional name calling in my defence.
I still haven't heard anything from either of them, which I think speaks volumes. I may be completely wrong but I suspect they and my sister will have closed ranks, agreeing with each other how unreasonable I'm being and it's not their fault that we can't afford to come along, and how unfair it is that I'm making them feel bad about going on holiday.
To answer some questions:
They did give consideration to what was affordable though she was pretty set on a particular type of holiday - 5 star, all inclusive. We were told to set our budget and they'd operate within that, which they did. They put a lot of thought and time into finding something that would work for us all, kids included. Where it went wrong was when they booked something different...
The more I think about it, the more crazy I feel it was in the first place... expecting your kids to spend so much money to celebrate your birthday. When it was first mentioned, I suggested a house in Cornwall. Clearly I was off the mark. There's no way I'd expect my kids to have to spend so much to celebrate my birthday - if I wanted it to be a family occasion, I'd be paying.
In fact, was talking to my son about it as he wanted to know why I was so upset. I explained the situation and even he was stunned. In his words, 'but you'd never do that to us, and she's your mum!', which I felt said it all.
As for them wanting a child-free holiday, I honestly don't think they did. I genuinely think they wanted us all there, and they did a lot of research into places with facilities for kids.
Miranda, yep, the seating issue upset me. Shows how much value they place on us versus my sister. Yes, there's more of us, but we're a package and as DH says, the upgrade would have been a huge benefit to us more than the kids. Even if he'd said, look there's 6 of us, I'll go halves (which still wouldn't have been doable, but it would have been a gesture...)
Shumpa actually, you have a point. Usually, my parents are quick to sort things with money. They'd rather buy the kids things than play with them. They're well off enough to have offered to 'fix' this by offering to pay the difference for us, but they haven't. Don't get me wrong - I don't want them to, it's gone too far now, but it's noticeable that it's not been offered as a way to make it all go away.
AveABanana, I think you win comment of the year. I just might buy my own plate, but I'm not sure the spelling I'd want would be allowed by the DVLA.
ItsNice, I'm so sorry you're dealing with similar. It stinks doesn't it? And yes, if it was just the holiday that would be one thing, but it really, really isn't.
juneau you've hit the nail on the head!
billy, thanks for asking. To be honest, I woke up feeling wretched again, but now, less so. You are all helping so much to know this isn't me causing a scene or making a fuss about nothing. They hurt me, and I'm right to tell them.
jjjjigoo I think you're right. I don't do this. Well, guess what... I do now.
gin thank you for the flowers. And yes, strip all the emotion away, they changed their minds and booked something different without checking with us. End of story. Yet, they definitely see things differently.
