On my Feb cruise on Spirit, I ended up with about 6800 points, which is the equivalent of running roughly $17k through the machines. I took $3k to gamble with and came home with every penny of it (thanks to the one low-volatility machine in the casino). I received a bounce-back offer the last night of the cruise for a free outside cabin, and my current online offer is a free interior on limited sailings next summer only.
