Oscar, nice write-up on the Tropicana. One of the reasons it got the "Tiffany" moniker is because of the barrel-vault ceiling of leaded glass over the casino tables. (Not actual glass from Tiffany, as far as I know, but it had that look). There's 2 pics of the glass ceiling on Wikipedia (See pics #10 and #11) --

And of course, the Trop history includes several CCA conventions too.
