Rewards questions

Hi everyone... So if I redeem a free night at the Mirage thru MyVegas how many more rewards can I redeem , like buffets ?? Also if I redeem a 2/1 buffet at the Beau Rivage (Biloxi) in November how will that impact redeeming rewards in December ?? Thanks for any help...
Terry, when you purchase a reward it will tell you how many rewards you can use within a 30 day period. If your November and December trips are over 30 days apart one will not effect the other.
