Yeah, it’s been a several weeks since I’ve really looked at booking Marriott (mostly due to lack of promo), but my experience from past several years has been that their AAA rates have provided the largest discount for cancellable rates between them, Hilton, & Hyatt. Would be disappointing if that difference has shrunk.

Hilton has been no benefit from the times that I’ve checked (basically AAA rates matches member rate).

Hyatt can be hit or miss. Sometimes member rate is cheaper, sometimes AAA is.

And as mentioned occasionally AAA rates have extra benefits included, such as parking, as well as also occasionally more favorable cancellation policy.
