Hi Kathryn,
It's lovely to see a question from a fellow brit!
If you are wanting to add to your Cars toy and merchandise collection, I would definitely suggest a trip to
Disney Springs.
Here you will find a fantastic array of shops including
Once Upon a Toy as well as
World of Disney - the world's largest Disney character store.
I would also highly recommend a visit to the Cars Section at
Disney's Art of Animation Resort during your stay where your little Cars fan will be able to have their photograph taken with many life-size Cars characters including Lightning McQueen, Mater, Sarge, Doc Hudson, Filmore, Flo, Luigi and more.
Wishing you a magical holiday filled with memories which will last a lifetime!
Emma
