Update on Marriott Gosforth Park (Newcastle)
The lounge is accessible 24/7 and they always have soft drinks (7p, Pepsi) and water. During the evening, they also have beer and wine.
They serve breakfast in the lounge on weekdays. They provide snacks in the evening from Monday to Thursday.
When I made my reservation, I phoned them to ask if they will provide breakfast on weekends and I'm pretty sure the answer was no. However, when I asked about breakfast upon check-in, they immediately said that as a Gold member I could have free breakfast in the restaurant. I had breakfast on Sunday (September 18) without problems.
