Hi Analisa,
Thank you for your question.
Your first visit is going to be magical!!
Before you arrive, I would call the resort and let them know that you will be travelling with your mom who is 84 and that it would be very helpful to be close to the bus stop. They will do their best to help accomodate your request.
You can always
rent a wheelchair for your mom while you are at the parks, just so that she doesn't get warn out walking.
When you arrive at one of the parks make sure you pick up your "First Visit" button at Guest Services.
If you can, I would highly recommend
character dining, my family really loves doing that!
If you have any other questions, please let know.
Wishing you a very magical first visit!!
Carrie
