I've had the same experience with DF's family. They're against having to travel and us "planning people's vacations," which is complete nonsense because the only thing we're planning is the wedding.

It's their choice whether people want to turn it into a vacation (which many actually are surprisingly). DF flat out told his grandfather that the people attending should WANT to be there, not feel obligated to be there. And if that's how they felt, they shouldn't bother coming.
This gives us the opportunity to be with the people we are closest to, not someone's uncle's cousin's nephew we haven't seen in 10 years and dont even remember.

We're more interested in who we spend it with, not the number of presents we get...although prezzies are always graciously accepted.
If you've always wanted a Disney wedding, then it's YOUR wedding and as long as the two of you are happy, that's all that matters.
