When I bought my week in May 2008, I got 100K bonvoy points, and then was told I would get 25K points every 6 months for the life of the loan (I did finance my week, it was a Marriott resale week). So was promised to rack up extra 50K points every year. He showed me lots of the Marriott hotels and resorts that I could go to. I did use 270K points for a 5 night stay and 110K United miles in 2022 (when they still had the 5 night certificates for owners). Stayed in Italy 5 nights in a $650 a night beautiful resort with full breakfast overlooking Tuscan mountains, which was fabulous.
However, I only got the 25k bonus 2 times because of the financial fallout of the fall of 2008.
I have only one time exchanged Abound points for a small amount Bonvoy points to add to what I had (at the end of covid when I had extra Abound points to use), to be able to stay at the Cotton House Hotel in Barcelona, again an amazing property, full Spanish breakfast every morning, and upgraded room.
All this to say, there are still times when Bonvoy points though devalued can get you a decent deal. If it hadn't been for excess points due to covid, I likely would not have traded my abound points. I would rather earn the points via purchases, and getting 40-50K for sales presentations. I do miss that they don't give 75K in points anymore, however they were stricter in how often you could go to a presentation.
