We called Disney CRO with this question three separate times--twice we were told no, and once yes. Bottom line is, I don't think the people at CRO have any idea. We are going in April, and got sick of waiting, so we booked the package with dining and tickets through
AAA.
We have been Disney regulars for many years, and have never seen the confusion that has been prevalent since January 1.
For example, we called yesterday to book a Fantasmic Dinner package. Question #1 was: can we use MYW dining plan to book fantasmic dinner.
Question #2 was: Is Sci-Fi available for Fantasmic dinner package during our visit in April. (Sci Fi participation in this plan varies)
The first person we got at CRO said no way can a MYW dining credit be used for Fantasmic package, but Sci Fi was available for Fantasmic if we would like to pay separately.
Immediatly hung up the phone and called back. Got a different CM, and was informed that we certainly could use

the MYW dining plan for Fantasmic dinner, but Sci-Fi was not available.
The MYW plan for packages and dining seems to have thrown CRO into total confusion!
