I feel that it IS your day and YOU are paying for it so you should have what YOU want.
HOWEVER, do you want to possibly exclude those who cannot afford it?
My sister did a destination wedding in Belize. I am a teacher, my husband is an out of work contractor. My husband and I had to save for over a YEAR to afford to go to her wedding. She did not pay a penny of our trip. It ended up being over $7k by the time everything was done. A week long $7k vacation we could not really afford.
If it wasn't my sister, I would not have gone. I still think she was selfish in her location choice and many people she wanted to have there were not able to go due to cost.
Personally, I have no desire at all to attend a Disney wedding. I am NOT a fan of Disneyland at all.
