It's great the you're going over to help her, but I do have to wonder why you didn't offer that at the start? When she said the bit about "
Disneyland, the zoo park and California Adventure", why not offer at that point to at least give her the "lay of the land"? I get the concept of waiting for someone to ask and not pushing your own way of travel on someone else, but if you know going in that "she IS the type that will be MISERABLE because her kids wont get to eat with Pooh and friends. She will come home ranting and raving about what a waste of time and money WDW is. She will be shocked at prices,crowds and without a little education will miss out on the magic.", why would you walk away muttering instead of helping?
Not trying to be critical ... just wondering ....
