So out of curiousity, I priced it for my January trip, which so far looks like a solo trip. And while I do have an occasional adult beverage, it is rare. And, honestly, at Brown Derby my preferred meal is the Cobb Salad, aa Hollywood Lights adult beverage, and if I'm really hungry, maube some soup...so two credits just isn't worth it for that location. And other Signature places, like Tiffin's, I generally don;t spend anywhere near two credits, either. I generally have stuff delivered to make sandwiches in the room for dinner, so it just isn't worth it for me. And I generally eat at least one table service meal in the parks daily, including the occasional Signature restaurants.
But, then again, I've never been able to get the figures to add up for the Dining Plans.
