Hi Salma!
Welcome to the Disney Parks Moms Panel! So happy to hear that your husband is going to participate in a RunDisney Marathon! Yes, it is possible to only go to the marathon. When I participated in a RunDisney Marathon, I was not required to go to the parks or purchase park tickets. If you prefer staying at your
Disney Resort Hotel and not visit a theme park, that can be a lot of fun too! One of the things I love to do with my family on a day we don't visit a theme park, is to resort hop or visit other Disney Resort Hotels. We enjoy trying the different restaurants and visiting the different shops in each resort. I also want to recommend that you visit
Disney Springs, where you will find many restaurants, stores and great entertainment!
Since you are sending us this question from Mexico, I wanted to also let you know that the
Disney Parks Moms Panel is now answering questions in Spanish! Please feel free to check us out and if you have any friends or family that would like help planning their Disney vacations in their native language, send them our way as well!
Salma, it has been my pleasure assisting you! Thanks for sending your question to the Disney Parks Moms Panel!
