Ah. I'm not much of a slot player. Google tells me session points are either 1:10 to tier credits or 1:7.5, although that could be because the number depends on if you're gold or platinum (both of whom earn points faster than sapphire and pearl). If it's 1 session point : 10 tier credits, 1250 session points would be 12500 tier credits, or $2500 coin-in per day -- which, by my calculations at dollar slots, gives a comp value comparable to midweek rates at ARIA. Which makes sense, so 10:1 seems to fit.

As I understand it. -- 40k tier credits over three days or less should have gotten you the room comp. So I have a few questions:

How many days were you there? Did you mix slots with tables or VP to get that 40k tier credits? What's your guess on the session points you earned for that 40k tier credits (ie the session points : tier credits ratio)?
