Hi Kristin!
Yes, Teppan Edo is
not currently on the dining plan for 2012. There are many non-Disney owned restaurants that are not yet on contract for 2012. They renew their agreement each year with Disney, and that usually takes place during the last part of the year (November/December time frame). Teppan Edo has been on the plan in the past, and I feel rather confident that they will re-sign for 2012, as the Disney Dining Plan is wildly popular.
Hollywood and Vine is currently a character meal at Breakfast and Lunch
only. These things can and do
sometimes change, so just keep that in mind. I've not heard anything about a change though, but if there is an announcement, it will likely be posted on the
Disney Parks Blog.
I've double checked with dining, and they are showing availability for Breakfast, Lunch and Dinner in March 2012 (we looked at several different dates during the month of March as well).
Have a magical vacation!
Amanda
