I have decided that I am going to complete the Diamond Trial to throw a bone to Hyatt for helping me save a boat load in Tokyo this fall. My only question is how I should best time my mattress run.

I plan on staying 15 nights to hit the challenge, and to get a good points break on the Endless Possibilities promotion currently going. Will these stays count towards earning Diamond status beyond Feb 2105? I ask because I may want to break the 15 days into smaller stays to count towards the 25 stays required by Hyatt for Diamond.

Thoughts?
