Amusing thread... that shows how confusing Hilton has made things...

My understanding is that 2020 rollover nights are worthless for determining how many nights will into 2022. Rollover nights ONLY help you reach targets when you wouldn't otherwise get there. They don't help you retain Diamond indefinitely. Otherwise a "credit card Diamond" could say "well, I'm already Diamond so I needed zero nights --> everything rolls forward a year"

In other words, only the actual 2021 nights in bed above 30 will rollover to 2022 for Diamonds.
