If I were there
I'd camp out. I primarily play $5-$40 or $50 DD games, or $10-$40 SD games, so it would certainly be interesting for me. Even on the occasions where I play $25 min tables, another $25 per hour would get my attention...
But I have never personally played such a promo unfortunately. Played quite a few matchplay type opportunities, and the coupon promos where your first snapper pays 2:1, etc. But nothing quite like this. Maybe I'll get a chance one day...
