no, I really don't think it's worth it
...I know we're in the minority but we didn't think the food at CG is worth 2 table service credits. Also don't think it's worth paying OOP either. We've had similar or better steaks at the one table service restaurants like Le Cellier, The Grand Floridian Cafe and Kona Cafe.
We also don't care for spending 2+ hours for "fine" dining. We're not wine-sippers, so the long waits between ordering & receiving the beverage, then hurry up & wait for the entree, then another 30 minutes to wait for the dessert was just a waste of time to us. The service was attentive, and polite, but there was absolutely no point in the time involved, IMHO.
You're really paying all that extra $$$ for the view -- and you may or may not actually have a view when you're there. When we were there, they actually had the blinds down! So we had a window table, but couldn't see a thing. When we asked why they were covering the view, the reply was "we'll raise the blinds when the sun goes down." What!!! Apparently enough people complained that they eventually raised the blinds about 10"...so if you scrunched down in your chair you had a view. Hardly worth paying so much for the view, though.
