Tender Tickets on Celebrity Infinity

How does the distribution of tender tickets work on Celebrity Infinity? We will be taking a Pacific Coastal Cruise in September and will be tendering in Santa Barbara and Monterey. We will not be taking a ship excursion, but will be renting a car privately. How can we insure that we can get an early tender?

As this is a Celebrity policy and procedure issue, and their tender policy is the same worldwide, I would be asking this on the Celebrity board.
