Thanks! Transferred the remaining M points back to *W that was just enough to book cash and points stay at Four Point Auckland. The hotel will move up from Cat 3 to Cat 4 on 8/1 so just in time. Now I have several floating Marriott certs that I could not apply to Sheraton Taipei for fall travel. The certs clearly states:

Reward Details
· Description: 7 Night Travel Package Category 1-5 Hotels
· Reward code: 830T
· Valid through: Saturday, July 20, 2019
· Total points redeemed: 540,000
Confirmed on: Friday, July 20, 2018

I am wondering how can Marriott legally cancel these certs? They are confirmed on 7/20/18, which is more recent than the dates of any posts about cancellation and refund after merge.
