I haven't seen such an offer in a while. Usually, it occurs in markets such as Atlantic City.
With that being said, it's really easy now to make diamond in one or two days of play at a CZR group property.
Diamond isn't particularly valuable. Everything is based more so off of your theo, so without a good theo; it's just a bit of "line cutting" and diamond lounge access. In the Vegas markets, the diamond lounge experience is very limited (and sub par). In Atlantic City, it's also not so great (but better hours on the weekend); but you are charged per visit until you reach 25K tier.
The only worthwhile benefits (and lounges) in the CZR system are the 7-star lounges. But, 7-star is hardly worth the (stated) benefits.
