It is not on the dining plan. It is, however, relatively easy to get into. They do release some of their ADR's to the Disney Dining line, but you can also make reservations calling the restaurant directly (they have more reservations available at the restaurant level from what I've read)
I've never heard of more than an hour wait, at the busiest times for dining. Usually the wait seems to be pretty minimal there.
So if I call directly they may have some availability? Right now there is nothing showing for dinner on the night I want to go on the Disney site.
Yes, call the restaurant directly. They only release a small amount of their reservations to be booked through Disney.
We are eating there August 15th, and when I called 90 days prior, WDWDINE told me that they don't book ANY of the reservations for TRex, and I had to call the restaurant. Of course we know that the CM's give conflicting info, but I think calling directly would be your best bet.
When I called directly to make a ressie I was told you don't have to make a ressie, that 70 percent of their seating is walk-ups.
