The Chase Ritz-Carlton includes a priority pass membership, there is no limit to the amount of guests you can bring in making it the best Priority Pass memberships offered on a credit card. Up until recently the one downside has been that you haven’t been able to get digital membership card (despite the Sapphire Reserve getting this functionality added last year). I’m not sure exactly when this changed, but reader Miro noticed they were able to register and Chase confirmed this. Cardholders can register here.
Not all lounges accept the digital membership, so holding onto the physical card and keeping it in your wallet is still necessary but this is still a nice back up plan to have activated.  Unfortunately it looks like you need to set up a new account, as I don’t see anyway to add it to an existing account.
