Bought Sterling Membership in 2012 and till now regretting for the same.. When I bought the membership I was told that the Annual Subscription Fee will not go up (it was around 8K) but now it’s more than doubled.. they also went ahead and cancelled my credits for Covid period and whenever I wanted to travel after that, they never had rooms, but for the same days I was able to book rooms in Sterling using Booking.com - this is how they cheat their members.. they are also quite rude and once you become a fully paid member, they treat you like slave.. please don’t fall for there marketing gimmicks.. also, I think planning trips every year for 25 years is not possible and hence be prepared to lose some credits..
