There's a whole sticky thread over in the Marriott forum about which lounges are open on weekends. My only weekend experience with Hilton was in Paris, and the lounge was certainly open (Tower Hilton).

Planning out a trip which will include Hiltons in Budapest, Paris, and Rome. I'm sure others might be intersted in these and the rest of the Hilton properties.

Is there a comprehensive thread regarding this matter (I searched and couldn't find one), or are the lounges open on weekends as a matter of course?
