Hi, Shelley!
I'm excited you are interested in taking on runDisney's ultimate endurance event, The Dopey Challenge. As a Dopey Challenge Finisher myself, I know how nervous and excited you my be feeling as you prepare.
I highly recommend staying on property! And with all resorts serving as "host hotels," transportation to all race activities will be provided. My favorite resort location for Marathon Weekend is the Epcot Resort Area. I love feeling like I'm in the center of the magic. In addition, the dining, recreation, entertainment and pool areas at these resorts are the best on property - and Epcot® and Disney's Hollywood Studios® are within walking distance. Disney's Beach Club Resort is my favorite of the available options. Here are a few other suggestions for my
top resort choices during a runDisney race weekend. Just select the highlighted link to read all about it.
If the merchandise at the Expo is important, arrive late on 1/3. Otherwise, early on 1/4 would be just fine. If you're not adding additional vacation time, I would depart on Monday, 1/9. After 48.6 miles, you will need the rest of Sunday to begin the recovery process. And if you plan on adding in vacation days to visit the theme parks, do so after the races.
As for your family, are they interested in spectating any of your races? If so, there are packages available that will provide them an excellent experience during their wait to see you pass. These "ChEAR Squad Packages" offer varying levels of perks to meet your needs. Let me know about your family and we can create a plan for them, too!
I hope this helps get you started, Shelley! Please reach back out to me with any additional questions. I am here to help make your runDisney experience magical!
