Why are there so fewer participating restaurants listed in the 2017 disney dining plan? I don't even see via napoli or tokyo dining and only one restaurant at Disney Studios.
Also note that except for a restaurant actually closing, the grand total of restaurants that have ever dropped from accepting DDP is, last time I checked, one.
Unless you're hearing a seriously strong rumor to the contrary, assume a 2016 participant will continue in 2017 (barring scheduled closure).
