Gene,
The Lederer/Duke productions were called Fantasy, the WPT productions were/are called Boot Camps.
This might be splitting hairs as far as Rick's question goes, however, the two are competing enterprises and, I would guess, the experiences would be significantly different.
From my recollection of dealing during one of the Lederer/Duke camps, the main draw of the fantasy camp was that there were MANY professional poker players involved. I'll likely miss a lot of them but there was, of course, Howard and Annie, Huck Seed, Phil Gordon, Chris Ferguson, Erik Seidel, and Gus Hansen. I seem to remember Andy Bloch but maybe I'm getting several events confused....it's been what, two years? Anyhow, the kicker was that when the participants played a sit-n-go one seat at each table was reserved for a pro. At the conclusion of each and every hand there could be a question/answer period about how the hand played out, how it should have played out etc. etc.
I have NO experience with the WPT camp but if their camps consist of one or two pros I wouldn't think the participants would get the same small group quality time with their heroes.
