Got matched to Hilton diamond, from BW Diamond (that I got from spg gold).
Also got Sixt Platinum, from BW (if it's worth anything).
Now let's see if Hyatt will match me to Hilton.
Marriott didn't, and spg offered a challenge, 18 nights in 90 days for platinum (as expected).
Let's see if this works. I got Best Western Diamond by asking them to match my SPG gold (that I got from my Amex platinum.)
Now I just submitted that BW diamond asking for HHilton diamond.
Thanks for the inspiration!
