We were there last year in May and gave Council Bluffs (both at HS and Harrah's) for about 3 days and never really got any good offers. I think the most is $50 fsp and 1/2 off buffet. I figured it was because we went there on the paid airfare offer.
I don't think we have anything at Council Bluffs now. Sometimes if it has been over 13 months - CET will quit sending you offers for that property. I didn't get anything from Tunica after about 13-15 months of no visits there.
Are you still getting offers from Bossier City after your visit there last August?
