Hi again, Ricki!
This is another excellent question! I'm very excited for
Mickey & Minnie's Runaway Railway, which will be opening on January 27 - just two days before your arrival at the Disneyland Resort. As much as I wish I had the inside scoop on the details of how they will handle the opening of that ride, I, unfortunately, do not know. (My guess is that information is still locked up in Scrooge McDuck's vault.) All I've seen mentioned so far is from the
Disney100 overview where they mentioned the opening date for the attraction.
Having said that, it is opening in just a few short weeks, so I would imagine more information will be released soon. I'd recommend bookmarking the
Disney Parks Blog filtered specifically for Disneyland Park news. My guess is that there will be more information posted there! Another great spot to watch is the
Disneyland Instagram account.
Keep those questions headed my way, Ricki! It has been so special to be able to help you plan all the details for this upcoming vacation of yours, and I'm positive it is going to be extremely magical.
Have a Magical Day,
Greg
