Booking online is different from booking by phone. It may not connect for that particular discount when you are booking a package from the website unless you book it as a room only first. But when you add tickets and dining it does become a package. If you're an AP holder and you add dining, it becomes a package. Unless you're
DVC you can't have dining added without making it a package. If your discount carries over, great, but it's still a package.
This is important because package reservations have very different policies regarding deposits, payment, and cancellation than room only reservations. Someone may go this route and then not realize they have to pay it all off 45 days from arrival, or there's a cancellation fee within 45 days now that it's a package.
