I feel the same exact way about family NOT being able to come because of their budgets. But this is something my soon to be husband said to me. "In the end it is going to be OUR wedding, and OUR dream...yes we love our family and want them to be there but we should do something together that both of us will love." Aside of having to pay for our parents all the others will have to make the decision on coming.
Picking a place has been thus far the hardest part of my planning. Everything else is easier in my opinion. Good luck, im right there with ya!
