I agree with that assessment on normal LE releases. But having such a concentrated number of collectors and dealers in one location, would lead me to believe that the participating casino could generate much more revenue in direct sales than they could generate at their own property, even with the extra gambling/food revenue.

I think in this situation, chippers would be running from one casino to another in order to collect the releases. Not giving much rest to gamble or eat.

There will be other LE releases during the year to promote the casino. But I would think a convention like this would be a goldmine, for the casinos to attend.
