My family will be visiting Paris later this month and are planning on staying at the Marriott Rive Gauche using points. We have the option of paying for an upgrade to an Executive room with lounge access for 50 Euros night. Has anyone stayed there and upgraded this way? Is it worth it? We have two rooms (four people) and I am not sure it is worth the extra money.
Are there reasonable places nearby to grab breakfast and snacks on our own for the day?
