Hello Mark and thank you for asking the Disney Parks Moms Panel such a great question.
I think it's so innovative how
Test Track Presented by Chevrolet works and allows Guests the opportunity to design a virtual concept vehicle then board a
SIM car to test it's track performance; so clever!
Your question was interesting because I was unsure as to whether Guest's own design concept vehicles were stored indefinitely on their
MagicBand; I spoke on your behalf with a knowledgeable Cast Member by calling 0800 16 90 749 (help with
My Disney Experience) who informed me they are simply stored as a '
one time ride experience'. This means upon your return to Walt Disney World Resort this coming August you'll be able to repeat all the fun you had last October by designing an all
new Test Track vehicle!
You'll be happy to know that functioning
MagicBands are indeed fully re-usable if they remain linked to your
My Disney Experience. If I can help you further plan your upcoming August holiday to Walt Disney World Resort please come back and ask me another question.
Have a great Disney day.
- Jane
