No, club level for just Marriott members but the hotel is very accommodating to members. They will assist you with as much of their authority as they can for instance my mother has Alzheimer and having a hard time with going inside the hotel to the room. The bell men parked the car and took the luggage to the room and would not take a tip then he always parked my car valet at no charge. I hope this helps answer your questions.
