So as a Premier Platinum Elite with 189 nights this year, I'm still trying to figure out how the breakdown of the rules and how all this works. The sudden conversion seems a bit arbitrary and adding things like a "spend" requirement for getting to the Ambassador level especially in the first year or so after the conversion a bit onerous. Staying 150+ nights in a year should be qualifying, even without spending $20,000 dollars.
Of all the things the Ambassador level offers the 'your 24' perk would be incredibly valuable to me, since I have odd travel schedules and being able to get in early and out later than normal (4pm) would be helpful sometimes.
Also the "rewards" such as Five Suite Nights are not available yet or are they?
