OK, I just went back to Expedia to look at this again, and here's why I personally will not use Expedia for the FT package. First, payment for the entire cost of the package is due upon booking, whereas only a $200 deposit is due if booked through DU or Disney. Second, any cancellations are subject to penalty, minimum penalty is $50/person. There is no penalty for change or cancellation through DU or Disney if made 45+ days before arrival. These restrictions aren't worth the $34 savings for me.
Hope this info helps someone else.
