Sounds like things vary, since the FTer staying there in July posted that the lounge was open 7days. Realize the website should match what is actually occurring.

The lounge can be busy in the summer when so many elites are on holiday with their families and while it's an ok size, if you've got lots of families of 4 + regular biz travelers, can see how it gets crowded. It's a bit that way during the trade show I attend. Most of the time there's not a 15-minute wait for tables, and luckily I've not experienced rock hard meatballs.

My suggestion to the OP would be when in doubt, email, fax or call the hotel directly. Cheers.
