Question about Fremont 33 free spins on $1 777 machine offer

Has anyone stayed at the Fremont on this offer? Is the machine a "real" machine or is it one of the rigged "promo" machines (aka Hooters free play machines) that do not actually pay anything out in reality? I ask because I have the offer for 3 nights with the spins on specific dates, but also a general 3 night comp at Fremont any my ideal dates would be a couple days different from the 33 spins promo dates. If it is a true dollar machine where you can keep any winnings from it, then it may be worthwhile to rearrange my itinerary to stay at Fremont those three days.

 

I've stayed on this promo twice, they like to run it during the summer. It's the real deal, one time I walked away with over $200, another time I won about $30. They have a bank of about 8 $1 Blazing 7's against the wall near the host's office/booth.
