I agree with trying to fnd a cheaper way to go.
As far as the comment, if you haven't seen them in seven years, make your decision if you want to move on: This is family- sometimes I go years without seeing family but I don't cut them out of my life. It doesn't mean we don't care for and love each other, we are just separated by distance. Our family does use weddings as mini-reunions. I planned mine both date and time wise specifically so family from out of state would have an easier time making it.
To the OP, good luck with your decision. When I got married, my dad did pay for the rooms for my family from out of state. we had figured it into the cost of the wedding b/c it was important to us for them to be there. I hope you can find a way to be there, if that is what you want.
