Hello Judith!
If you are looking for a great resort to stay on a budget, I would HIGHLY recommend staying at a Disney Value Resort!!! There are three reasons why I say this:
1. The price of a value resort is very affordable on any size budget!
2. You have access to FREE bus transportation to and from your resort to all of the Disney Theme Parks and Downtown Disney!
3. You are able to take advantage of getting in the Disney Theme Parks an hour before they open and three hours after they close on certain days called Extra Magic Hours! (AND it gives you more time for you and your granddaughter to spend with Cinderella!)
For complete details about all the Disney Perks you receive when staying at a Disney Resort, click

I hope this helps in making your decision!!! If you have other questions, please let me know!
Have a MAGICAL day!
