I just got an email from CET for some bonus free slot play that's good for only this weekend. Is this considered in addition to the free slot play they've already offered me for the week or could I only use one free play offer at a time?
It depends on the offer. Some casinos let you stack FP. Some are tied to a hotel/offer and you pick on or the other. What does it say? What hotels? Are stays required?
No stay required for either my weekly free play or this free play. Both are casino-specific to Caesars. I just got this email and it called it "Bonus Free Play" for that specific date.
