Aww hun, I know we had the exact same problem as you.
We are now going only with a short list and I'm paying for my sister, BIL & baby to make sure they can come.
I was rather annoyed at my Dad though because he kept asking me to change it to Florida when that's really not my thing. Other people are saying oh you can't stay on the same resort for 2 weeks all together! Grrrr. What ever happened to it being the wedding we want?
I'm sticking to my guns though, we're sending the save the dates out in March next year and then just seeing who goes! Part of the good thing about it is you don't have to pay for all the food because it's all inclusive anyway.
Our list only goes as far as:
My side:
Dad & wife
Sister, BIL, Baby (dont know if its a boy or girl yet)
His side:
Mum & Dad
Sister, fiance, baby
Brother
Gran
Auntie
Then there's the reception back home which will be a buffet style one to suit our style:
Approx 60 people.
We don't think anyone apart from his mum & dad will go on his side and 4 people from my side! But we're past caring because everyone will be there to celebrate when we're home. As long as we're married and the day is amazing then I'm happy!
What are you going to do then?
