Since we particularly dislike children coming here, there are many bars in which you can enjoy a large, refreshing, glass boot of beer.
There is also a large cable car in which you can travel down to the nearest city in Germany, just in case you want other human contact besides servants and guards.
If you get bored of these two things, there is a large courtyard behind the castle in which you can learn to ride a horse, or just ride a horse yourself. You don't need any human company for this one; just you riding your horse all day.
If you still don't enjoy the sound of these activities, you can simply visit our in-door (I guess you can say our in-castle) museum. It has historical object that date back centuries; from when the castle was built and who lived here and whatnot. There is even a gift shop where you can buy minature versions of the artwork and historical objects to brag to your friends and family where you've been those past couple of weeks.
