As Aaron Burr was quoted as saying: Don't do today what you can put off until later as things may change and make your decision foolish. (Or something like that!) Spire is extended until 2/23 so may not need AMB next year. Of course, there is no written provision for the Spire extension with AMB renewal, it just has always worked that way, at least since 2016, the last year I actually did 75 nights. Last year's AMB renewal generated about a $250 benefit over cost: $75 cost/value for the 15k points, plus got the 25k Spire renewal benefit for another $125 apx, and the BOGO saved $250 at the IC SF. Of course, I had few paid IHG stays in 2021, actually just the IC SF, concentrating mainly on Hyatt and Marriott while burning through a great number of IHG points in Sept and Oct.

AMB and Spire may not have much in the way of benefits, but at $200 per year, it's too cheap to pass up in order to get a mid-level status in IC and top level at IHG. It's always been worthwhile for me. YRMV.
