I'm not sure I would consider carnival rides even a c ticket. .
Using the "E" ticket analogy, it's awful hard to define what something is once it's less than an "E" ticket.
Original MK "D" tickets: Skyway, WDW RR, Mickey Mouse Revue, Mission to Mars, Admiral Joe Fowler (Riverboat)
Original MK "C" tickets: Grand Prix Speedway. Peter Pan's Flight, Snow White Scary Adventure, Mr. Toad's, Swiss Family Treehouse
Original MK "B" tickets: Main Street Cinema, Dumbo, Mad Tea Party, Mike Fink Keelboats, Frontierland Shooting Gallery
But looking at that list, if they put something similar to the "Bug's Life" Land like in DCA - I would agree it's probably a C or B ticket...
However, I've said it before in this thread. I think it's perfectly fine to put some kids rides in this park. I would hope they were a little more inspired than another Dumbo or Tea Cup style spinner, but DHS does not have enough rides (or entertainment in general) for little ones, and that would help remedy that. Several kids rides IN CONCERT with Star Wars expansion with another E ticket + C ticket and maybe a new show and restaurant would work fine for me.
