Apparently the Armar House in Cancun (has been rebranded a few times in the last 5 years) is being renovated into a W All-Inclusive.
Most all-inclusives have a Club level. Royalton calls their's Diamond Club. Club rooms at AIs usually include a club-specific restaurant (even if only for breakfast), dedicated beach area and pool, lounge with premium liquors, and other assorted amenities.
Here's the Hideaway at Royalton Riviera Cancun's club benefits as an example.
If these were more deeply branded (e.g. not an afterthought like "Hideaway at Royalton Riviera Cancun, an Autograph Collection Hotel" but rather something like "Marriott All-In Riviera Cancun"), I'd expect them to extend that club benefit at a Platinum or Titanium level. Given it's Autograph (I really want to write AC but know it'll be confusing), I wouldn't expect to get upgraded to a club level room.
That's surprising to me, namely bc the Chic resorts are kinda meh for an AI. If the JW is just "a bit nicer", you might want to consider one of the higher-end AIs next time (TRS Coral, Excellence, Live Aqua, Secrets Playa Mujeres, etc.) if the price is right. The Hideaway location above might also tickle your fancy if you want somewhere to earn/burn Bonvoy points.
