Glamping Options

Wacken 2025 will be our first time attending. My wife is incredibly excited to go for the first time. I am happy to join but am looking to do RE or Moshtel campsite for peace of mind since we're coming from the US.

My question to those experienced can I purchase a general entry Wacken ticket now then the campsite package later, or do I need to wait until the campsite pricing is announced?

Thanks for any help!
