Hi Colleen!
How exciting to get to stay at
Disney's Art of Animation Resort, the newest one to be added! I am so anxious to see those rooms in person myself!
The answer is yes, you can upgrade to the Disney Deluxe Dining Plan for an additional cost.
I went ahead and contacted Disney Dining, who put me through to the Art of Animation Resort, and was told that you would need to speak with whomever it was that you made your reservation through in order to get the pricing for this upgrade.
If you have any problems with this, please don't hesitate to let me know, and I'll be happy to try to help you through the process.
I hope you all have a magical time at Walt Disney World!
