Disney is the most wonderful place to eat out with lactose intolerance, or any food allergy type problems. I too am lactose intolerant and have had wonderful experiences at Disney. Have them note on your ADR that the children are lactose intolerant. Remind them when you check in. The chefs are great at walking you through buffets. If it is a breakfast they will offer to bring out special waffles from the back. At most places the waffles will not be Mickey waffles, BUT at Chef Mickey's they will fix lactose free Mickey waffles!!!
At Boma, the chef made me a wonderfully yummy peach sorbet for dessert and brought it out to the table herself.
Also, at all counter service places, there is a notebook that lists all the ingredients for all menu items. Just tell the cashier about the intolerance and they will call up a manager to go through the notebook with you.
I was told that all of the french fries at WDW are dairy free and that all of the hotdog and hamburger buns are NOT. You might want to double check on this. I ate fries from several different places and never had a problem, but better safe than sorry.
Some places for desserts have special brownies that are lactose and gluten free.
And the ice cream shop on Main Street serves rice dream and soy dream (chocolate and vanilla).
Hope that helps!!! (P.S. sometimes it may take a few extra minutes for the manager at the counter service places to help out just because of being busy. Don't feel bad for causing a hold up in the line. Most people are very understanding and it's totally worth it!)
