I called 1-800-444-7646. I said I was a Wyndham Rewards Diamond Member. She asked how many nights I had stayed with Wyndham in the past year. I told her that I had two. She said I could be upgraded to Diamond status at BW. I asked what it would take to have Diamond Select, and she said 40+ nights. Status at BW was instantly updated from Blue level (where it's been for years) to Diamond.
