Granny - there is a vast amount of material and information re Walt Disney World at this website:
MouseSavers.com - Your source for Disney discounts, codes & deals!
There is also info re discount tix [not a big one] thru Undercover Tourist.
You might gain an entirely new insight about what there is to do there besides go to a park! Although I am more than aware how difficult it is to say no to any child re a visit to the house that the mouse built!
