I just hit 60 days with Hyatt, and have a cheap 10 day stay booked at the end of December at the Rio, but, I obviously don't "need" it. Not sure the additional 10 days is worth the additional rewards if not natural/organic. But to get a head start on 2026... yes. But my checkout date is December 31. If I booked a stupidly high rate for NYE, are we 100 percent sure I could convince Hyatt to count all 11 nights as 2026? I've done some Rio stays in the past that were combinations of 3-4 days times 3, and often after one or two of the back to back stays, they post before the third one posts, despite being consecutive.
