As someone who has paid $20-25USD for a single ride that I've already ridden many times before at WDW, 2000JPY feels like such a deal for a brand new ride
I am just crossing all my fingers and toes that they will surprise us and somehow keep the lines reasonably short. If the lines are crazy long, I imagine they would be dealing with lots of schedule conflicts as well, whether it be dining, other rides, shows, etc. They seem to think ahead on everything so I'm sure it will all work out in the end.
Now instead of playing the hotel rebooking game, I am working on my flights. Direct flights to HND from my airport just dropped to a reasonable rate (literally half of what it was before) so I am rethinking all my plans. Funny enough the one ways are now far cheaper than the round trip fare, I usually book one ways anyways.
