So as a long time plat SPG biz sleeper, these changes are HUGE and horrible. I normally do 30 to 35 stays and I get plat access that way. Now, it is all about nights and not stays anymore - which is a huge con to me. Also, liunge access at 75 nights ONLY? ..., again that is a huge con as well.
Whomever said, these changes are in step with what is there today is very wrong, in regards to SPG. SPG was the best system out there by far, these changes essentially demand 75 nights or spend your money elsewhere, which is bonkers, but hey that is life I guess.
