Hi Heather! Congratulations on your babies! You must be one busy lady and I am very impressed that you are taking on Goofy! What a wonderful accomplishment for you. I think it is so important for moms to stay active and take care of ourselves, as it can be easy to focus solely on our kids!
For marathon weekend, all of the
Disney Resorts will be host resorts. This means they will all provide free bus transportation to and from all race weekend events. Since they are all host resorts, you have the freedom to choose a resort based on budget and theme preference. The Deluxe Resorts are closer to the parks, but ALL of the resorts have free transportation methods right to the parks and Downtown Disney.
The new Art of Animation resort and some of the other value resorts do offer family suites which may be a good option for you and your little angels. It's a little roomier than a normal room.
If cost is not a problem, I love staying at the Beach Club, Yacht Club, or Boardwalk. They are all situated around a beautiful lake and it would be a great place for you to push around a double stroller! There are also several restaurants on the Boardwalk, and each resort has a great pool.
There are not any discounts for runners during marathon weekend. This is because there are so many runners and also because January is considered value season, so the rooms are already discounted off normal rates.
I hope this helps! Please let me know if you have any other questions as you prepare for your Goofy!!
