If for some reason I'm unable to bring the car I listed, do I need to update them to the replacement vehicle?
If possible do it ahead of time. But you can likely just go to guest services when you get there and they can probably accomodate you.If for some reason I'm unable to bring the car I listed, do I need to update them to the replacement vehicle?
I’ve done it multiple times, same result.I changed my vehicle type last year at customer service at gate 3. Took about 15 minutes.
Bingo, exactly. Go to gate 3 then guest services by the big stage when you go in the gate if you get there a day early on Wednesday or Thursdayyou can likely just go to guest services when you get there and they can probably accomodate you.
