Lacks Apple Wallet Integration

The only thing this app is missing is the ability to save your Marriott Rewards card to Apple Wallet. You can pull up the mobile card from within the Marriott app, but theres no option to save that card to Apple Wallet as there is with other hotels iOS apps (e.g., Hilton, Starwood, Hyatt).
