FoS motorcycle parking

[Durch]

Thanks to Pete V I am now heading to FoS on Saturday. I'm debating whether to go by motorcycle or jump in a car with others in my party. A couple of questions someone might be able to help with:

• are motorcycles permitted in the 'car' parking areas/fields?
• any rough idea how much time cars might queue for exiting at 17:00ish?
• would I need to take a shuttle bus to the proper motorcycle parking area?

I suspect the currently forecast rain will be the deciding factor.
