All I know is, the size of the queues for both of the main attractions will be HUGE. So they're going to be prepared for the crowds. Also, I do believe we will see single rider lines for both MK and DK, yay!
Yoshi, maybe since it's an omnimover, will actually have the shortest space for the queue of the three, but still pretty long. So, as I've said before, doesn't look like we'll be seeing any virtual queue for these three!
