Just got back from Vegas and they upgraded me from the standard Sapphire tier to Pearl. What room offers if any can I expect from this? I was pretty excited, I've been wanting to be above the normal tier for a long time, and even though it's only the next level up I'll take it.
If it was achieved via gambling and you started from zero you will probably get a few free nights here and there. Tier points are also gained by spending at 25 per $1 so it's pretty easy to hit Pearl if you spend more than a couple of days in a hotel and you're paying for your room along with a few meals charged to the room. I was Gold a couple years back and my offers weren't any different than when I wa ps sapphire. I hit gold mostly due to making a 3rd trip during a year instead of my normal 2. But like shifter said, color of your card has no effect in your offers. Offers are tied to how much you gamble.
IMHO, other than the line privileges and the Multiplier, there's no real benefit. You might get a few better offers where you play the most, but that's about it.
You'll probably get free nights here and there for Nyny, Monte Carlo, excal and Luxor. They'll be in the form of email offers. Where did you play the most?
