What constitutes "activating"? I'm considering an AP but we're not going until august. Can I use the AP for hotel discounts and locking in MNSSHP passes...can I do that without "using" my AP?
activating means, going, yourself the AP card holder to be, in preson to the front gate /processing center and getting a physical AP issued.
Yes you can book AP hotel rates before you have your physical card as long as you GET the AP on your trip.
No you can't get the WOC/MSNNSP passes before hand.
