I see when I log into my ALL account, they have a summary of supposed savings from the program. I'm not sure if it's accurate, but I clearly did find some good SNU redemptions.
The SNU numbers are clearly over multiple years, though I don't know how many. The Dining and Reward points, however, appear to be only for 2024 YTD. My wife has a similar summary on her account.
What this tells me, is that the SNU deals I found in years past, have all dried up. Because I haven't redeemed even a single SNU yet this year (although I completed one stay in 2024 which I booked using SNUs early last year), and I've made 6 bookings in the past couple of months for trips later this year and into next year, where the SNU price was more than (or about the same as) the price of just booking suite off the website using a promo and no SNU. I have 19 SNUs sitting in my account right now, and 12 more in my wife's account, with no ideas on how to use them, and I suspect nearly all will expire unused. That's sad.
