That's too much for club access. I get it free as a Hyatt diamond, but would pay no more than, say $40 a day, if I really needed it. Unless you're ordering expensive items (or drinking a ton), $75 or so will feed you for breakfast, lunch and dinner here. The lounge normally only gives you two meals. When I was there earlier this year, breakfast was in the Show Kitchen, and some hot items/snacks were available at happy hour.

There are some decent advance purchase rates here. I see a difference of 400 RMB between cheapest room, and club room. (1080 rmb vs 1480 rmb). You may also want to peruse the Hyatt forum some more, as there may a discount code that you can use. I think I used the Costco rate here once last year.

I will be staying in Shenzhen next month at both the IC and Hyatt, so can give you the IC review after I stay.
