AIBU about this family wedding?

[Benji13]

So dh brother is getting married next month.
All the family are invited and as it's not near home we are sharing a large house for the wknd. Dhs step mum has organised the house.

She has sent a group email stating how much we all owe and lists bedroom allocations with names against them. My ds is v put out - as am I to see his cousin and gf are invited whilst his own gf - of nearly a yr isn't. Why?? Seems v unfair. I'm also bit miffed we - dh me and 2 sons have been allocated the cellar bedrooms - restricted head heights for us - the tallest family- I'm 5 10 sons are 6 1 and 6 3. It was stated in the email how we will need hard hats - haha. We are paying over £300 for 2 nights - our allocation to the shared house rental.

Thing is do I say anything about either of these issues or do I just let it go? Dhs step mum is rather bombastic to say the least.

Rooms - could well just be a couple of tight spots? Not sure they'd be allowed to market them as bedrooms if they were wholly restricted height.

Any relationship of under a year at the point of the wedding is kind of iffy to be honest, NOT because of anything about the relationship itself, but because when you're putting the list together - one of the first things you have to do to see how far your budget goes - it ISN'T a relationship of a year. It's maybe even just a first date!

If my fiance and I kept spaces open for the people who were single at the point of our engagement, we'd have ten empty seats, and ten friends miffed as to why they weren't invited for the sake of an as yet nebulous plus one!
