Question about using rewards in 2 cities

We are going to Biloxi in October. I have bought 2 rewards for Beau Rivage. We are going to Las Vegas in December, will we be able to use 3 rewards then or do the 2 we used in Biloxi count towards our 3?

Thanks for your help!
You can use 3 rewards in a rolling 30-day period so you should be fine.
