I've done 9 nights so far this year. Here's my strategy going forward for 2017.
Try to combine crossing 30 nights with 5 brands at almost the same time to get two nights with 120 day expiration. So far this year, I've only had Hyatt Regency and Grand Hyatt. Will be at the PH Seoul in a couple of months. Will move my stay from the PH New York to Andaz 5th Avenue (this seems counter intuitive to Hyatt revenue btw). Then I'll have to do a stay at Hyatt Centric Miami or a mattress run at Hyatt House or Hyatt Place in Dallas.
After hitting 55 nights, I'm not sure if I really care to hit 60 to get the extra free night. Then next year, I'm going back to SPG to get Platinum.
