Alot of things factor in like...
Date & Time:
Season: whether it falls on a holiday
Type of reception: Sit Down or Buffet, Brunch or Dinner
What location:
Any Extras: Mickey & Minnie, Cinderella's Coach, DJ?
Is that 60 definite guests? I invited 50, only 35 came. Alot of people can't swing a destination wedding.
I had 35 guests as a 9am Sea Breeze Point Wedding, reception at Ariel's and a Lower UK Dessert Party. I cut costs by using outside floral, outside photography, an outside videographer and doing my own centerpieces. Our reception was a buffet brunch with open bar. I did a simple dessert menu at the Dessert Party with no alcohol. Since my wedding was on a Monday and in the am it was much cheaper then having an evening wedding on a weekend. I cut costs as much and the day was perfect.
Your best bet would be to call Disney FTW directly and ask for a basic idea of costs on the specific date & time your daughter's wedding would be. Prices change so often it's best to hear it from the horse's mouth.
Congrats to you on being Mother of the Bride!
