Greetings, Carrie!
How awesome you will be participating in the Walt Disney World® Marathon Weekend presented by Cigna® for your third time! I love to hear from runDisney repeat runners.
For those staying at a Magic Kingdom Area Resort located on the Monorail, it will be running for the race. If you chose to stay at the Polynesian, you're just a quick walk over to the Transportation & Ticket Center where you can access the Monorail to Epcot®. Form the Contemporary, you'll board the Monorail located on the Grand Canyon Concourse of the main tower--your next stop will then be the Transportation & Ticket Center where you can transfer to the Epcot® Monorail.
I say the splurge is worth it! And in my opinion, if you don't mind the construction that may be ongoing at Disney's Polynesian Resort, it is your best bet with regard to convenience and location.
Also, don't forget registration opens on Tuesday, April 22nd at Noon EST-- races are selling out at a record pace and I wouldn't want you to miss out on your opportunity to register. And don't forget to check out the
Travel Tab on the runDisney website, this is where any discounted travel packages available for this event will be released.
I hope this information helps answer your question, Carrie! Please do not hesitate to ask me any additional questions you may have as you plan and prepare for the 2015 Walt Disney World® Marathon!
Happy Training!
Faith
