free tourney offers after being backed off

Is it safe to assume a free tourney offer is going to be honored even if I was backed off from casino or given a "no more Bj"? I used to bet these offers and use them from Harrahs in LV w/out problem.

My second biggest worry- I show up they say management decided to revoke the offer.

Biggest worry- I start playing in tourney, spend hours playing, get to the final table, casino pit looks up my info., makes some calls, and someone tells I am not allowed to win anything at tourney.

If I should take offer, I would not any bj at this place during this trip.
