So I booked my room just using the CET calendar, no offer was used. I was just looking at my offers to see what was on there and I noticed this: "Come on over & receive.. $20 to play at any Caesars property in Vegas! Valid 03/01/13-03/31/13. Book this offer by calling 800-901-2912 and mention code: "(not sure if I should mention the code)". When you arrive for your trip, stop by Total Rewards to pick up your voucher!" So can I just call that number and they will give me $20 in FP when I get there? Also there is another one "Come on over & receive.. $15 to dine at any Caesars-owned outlet!" Does that work the same way, can I use both of those for my upcoming trip?
