I don t know the price of the executive lounge. But I definitely don't recommend the breakfast. Breakfast is served in a restaurant adjacent to hotel it is not the hotel s restaurant. Was not very inviting!
I stay at the Beijing Marriott Hotel City Wall that has a Chinese Name Beijing Pudi Hotel. The Marriott website has been down for a couple of days. The mobile site does work. You can call the local number in your country and the representative can assist you with contacting the hotel or try the SPG website and use their chat.
