Unless you willing tobet a minimum of $100, there is no blackjack at the TI
The high limit room has two DD and two 6 deck games. The minimum bet range from $100 to $300. Outside these four tables in the high limit room there are only CSM and 6:5 games at the TI. Several times when the high limit was completely empty of players, I have asked if I could play at a $50 minimum and was refused.
You will be better off taking the tram to Mirage and playing their 6 deck games which usually have at least a few with $25 minimum. The DD games are lowered to $25 in the early morning hours. I think your TI host can still base your comps on your play at the Mirage. Getting your coffee shop, California pizza, and Mirage buffet comped should not to difficult, but the room is doubtful.
I asked one of the dealers at a CSM game in the TI, if the MGM execs were trying to make most of the long time blackjack move to the Mirage. His response was, "I think they just want to run off anyone who tips".
