If you signed up and paid for them on line thru the ship, the tickets will be in your cabin when you arrive or your cabin attendant will give them to you. If you booked independantly, I would assume they will email or fax you info but I would not pay in advance for any private tours. Have a great time.

Look for your shore excursion tickets in a hot-pink envelope in your stateroom.
Also, your travel agent should have received a list of excursions you booked. If the agent didn't throw it away, see if you can get a copy of it. Or call HAL (206-281-3535, ask for Shorex dept) and ask for a fax, or else log onto www.hollandamerica.com and print out the screen that shows your shore excursions.
