Reanimating this thread:

I recently had a "legitimate" overlapping stay -- a 5 night stay in one city with the last night overlapping with a one night a short flight away. (I had to go to a meeting which required me stay overnight and didn't want to check out from my first hotel.)

Now that HGP is back online it's showing credit for both, and that I'm at 50 nights. This is great, as I was planning a mattress run this week to make up for being one short.

The question is, should I be concerned that Hyatt may claw back that last night as they work the bugs out of their software upgrade? I'd rather not do a MR "just in case" but I don't want to end up one night short of Diamond for next year.
