Thank you!The bands of course at the BC are your room keys, but any additional add ons such as park admission purchased not as part of a package can be linked any time. Usually the bands for a visit are shipped out up to 30 days ahead of your visit and are linked already to your MDE account (if you have one). "activating" a band is just linking it to your MDE account. Admission entitlements are just added to it.
