Hi Melanie!
Thank you for bringing your question to the Disney Parks Moms Panel. I'm sorry you haven't received adequate information thus far, but I'm hoping to be help fill in some gaps for you!
A vast majority of the
Good Neighbor Hotels at Disneyland Resort are within walking distance of the starting lines, so you shouldn't need to worry about a shuttle! If you would like to take a shuttle though, some Good Neighbor hotels provide a
complimentary shuttle which departs roughly every 20 minutes to the Disneyland Resort drop off area. A pass can be picked up at the Transportation Desk at the Expo during the runDisney Health & Fitness Expo. To get to the expo, you can show your printed out waiver to the shuttle driver. Once you receive the pass, you'll want to hold onto this for the rest of the weekend.
If you would like more specific information on your specific race weekend or the Good Neighbor hotel you are staying at, please come back and let me know and I'll try and provide more detailed information for you! With almost 50 Good Neighbor hotels and four different race weekends, it can differs between each.
