Actually, Hoop Dee Doo isn't that bad of a value on the dining plan. You're talking about a $60 meal, which comes down to $30 per credit. If you're talking about average prices for table service, that still puts Hoop Dee Do up in the top 25. As far as averaged prices go, the top 10 still hover around $34. So, $30 isn't too bad, especially when you consider that it's only $40 per day for the plan in the first place. For 'regular' signatures, though, you're unlikely to spend $60 on your meal, so those are much worse of a deal.
For us, though, we nixed 2TS credit meals because it meant we'd get to experience fewer different dining locations.
