I think they're different enough and I'd keep 'em! We love GG, it's much more relaxed than CM - you're not getting up and you'll have much more character time, at least we always have. The atmosphere at GG is really neat - just the fact that it revolves and you see the LWTL ride as well as the bustling pavilion, and you'll be served some food that's grown right there. That said, and as you know, CM is just so much fun, love waving those napkins, and love Mickey dressed in his Chef attire. Can't get enough of the desserts there either! Have a great time dining!!
