I have a friend who is going to be in this years olympia and our group are intending to go watch him.

Has anyone been to a mr olympia?
Is it worth going to watch all 4 days? Ex. On the 17th is Olympia Superstar Seminar. No idea what that is.
Should we buy the premium packages or is possible to see with GA tickets?
Is this like other shows where we should just plan on watching the finals or maybe meeting the competitors?
Any general advice?

Thanks
