Thanks for the replies all! I'm mulling it over a bit more but will probably keep the 5/24 slot for other cards in the meantime. I was trying to do a simple comparison as someone who doesn't stay in IHG properties very often nor use the 4th night free benefit (usually I only stay in IHG if I have points or the FNC):
​​​​- If I keep my Select (retaining the 10% rebate) and only churn the Biz Premier, then I effectively gain a 140k SUB which with the 10% rebate is worth roughly 155k points and my annual fee is $148 (Select + Biz Premier).
- Alternatively, if I cancel the Select, and sign up for both the Premier and Biz Premier, I'll be getting 140+175 for 315k SUB at $198 AF.
So math-wise, it's for me to decide if the 175k difference in points and extra $50 AF is worth more, or whether the 10% rebate + lower total AF is worth it I suppose?
