Once the dust settles in early August I’ll make some significant updates to this post (probably essentially rewrite it). You can still status match Ocean Prime in AC to MGM Gold through July 31st, however, you won’t be able to match that to Hyatt after July 31st and your status will still expire July 31st, rendering that useless, unless you have never had a Caesars card in which case it would be useful (for those two weeks) to get MGM Gold and match to Caesars Diamond which would be valid through Next January. Friday July 14th is your LAST DAY to match between Hyatt and MGM (either direction) if you haven’t already.
July 14, 2023: As anticipated, the MGM and Hyatt Reciprocal match is dead. There is was a rather crazy MGM Status Challenge which expired Sept 30, 2023 July 27th, 2023: MGM is no longer matching at all. I’ll be dialing into this in the coming weeks and rewriting this all for what is available as of fall 2023.
