janfred - The Star Princess has two 18 day itineraries scheduled for August 2010 which include a lengthy land tour option with travel to and tickets for the Oberammergau Passion Play! My lottery tickets have not hit yet - so it looks like I'll have to wait it out.
I believe it is necessary to make arrangements directly thru Princess for the combined sea/land package as it requires disembarking for 8-10 days for the land package. In any case your TA will probably be the best way to make the arrangements!!
