processing platinum pass and early entry

If I buy a Platinum Pass online for CP and show up for early entry on my first day of my trip using it will I be able to get in and have it processed at my convenience before I leave the park that day?

I just don't want to be held up on my first day there. Especially getting in the park early.

thx

I think they open like half hour before the park opens maybe and hour.

I know that my family loves to make a special trip to get our passes processed and we meet up with my sisters family and grab a bite to eat up there! I love to say hi to the park before opening day after not seing it all winter.....
