I only stay there one time so not sure how things work between the hotels now that it seems Beaux Arts seems to be more independent of Marriott rewards. When I stayed there, Beaux Arts did not have a work out room or pool. One was allow to use the JW facilities, which is huge as it includes two full floors for recreation. My room key also allowed me to enter the JW lounge, which is much large than the one in Beaux Arts. The food between the two lounges are quite different. Would love to stay there again, but Beaux Arts no longer accept Marriott reward stays.
