New Event Planning

So the goal is to start a new venture of event planning on a shoestring budget and starting this year add an event every year. CURRENT IDEAS ARE:
  1. Game of Thrones event
    This would possibly be the most expensive one because I've actually found a castle we could rent. Is it worth $50 a person?
  2. Group Camp Out
    Prolly one of the least expensive, but other then karaoke, some live music, a big fire struggling a bit. Is that enough?
  3. 80's or 90's themed pub crawl? Seems too easy, but still good idea.
  4. Plug n play Group
    Buying a bus a building a group large enough to have our parties within existing tailgates or festivals or beach. As I typed that the idea felt really good!
