yep, i agree it's a little confusing
Though the big river grille restaurant
is on the
ddp, it is not a disney-owned restaurant, so you can't call the disney dining reservation number to get adr's there.
The big river grille books your reservations through it's own reservation system instead of disney's. You just have to contact the restaurant directly to get a reservation. Info is:
Phone: 407-560-0253
fax: 407-560-8780
hours:
Sun-sat: 11:30 am - midnight

again, there's no problem using the ddp there, you just can't get an adr through disney...
