Seminar Reviews - FTU and such...

Howdy folks. I'm looking to take my Game to the next level, start networking, and find good seminars to attend. If any of you have attended any Points/Miles/Travel Hacking seminars, I'd love to hear your thoughts. And just to be clear, I'm not talking about the "sales" seminars offered up by hotels, but the FTU-type seminars offered up by the bloggers.

Any input would be appreicated...any level of detail would be appreciated too - just knowing you loved it or it was too basic would be a huge help. Worth the time and money? Any specific presenters memorable? Forgettable? Also, curious if these are just one big clique or if they welcome "newcomers".

Thanks in advance for your input.
