Adding Extra Items After Initial Registration
You can add any extra service
or merchandise item later if you
are unsure about it when you initially register. The
availability of all extra service
or merchandise items are guaranteed until the regular
registration deadline unless stated otherwise.
We strongly recommend signing up for all extra services and
merchandise items once you're sure you want them though
so you don't run into any potential availability problems
After the regular registration deadline, extra service
items may not be available and an additional administrative
fee may apply.
