I attended the 2012 Bundeschampionate as an owner and actually had the honor of winning. :-) very exciting to say the least.
As an owner you are provided entry - which was a great perk.
However - tickets do not need to be purchased in advance. There is a ticket office open at the front and you can purchase a day pass or a week pass.
The only seats that are "assigned" are in the jumper arena.
In the dressage arena, pony dressage arena and in the young horse arena - it is open seating. Same for driving and eventing.
Hotels book up yearly in advance within a 30 minute drive range. Many people just reserve rooms for the next year when they check out.
We stayed in the east side of Munster area (near the Westfalen offices) and just drove each day. It was about 30 minutes drive.
You will need a car and parking is in a field across the street from the entrance.
