The biggest negative this year is that many areas have been combined. I went to Reno, Tahoe, Vegas, Laughlin, Phoenix Ak Chin, and San Diego Rincon last year for six visits, which earned the top level of 60K.
This year, that same trip counts for three visits and six checkpoints, earning only the lowest (10K) level.
You also have to earn 25 reward credits at a single property, rather than just 1.
