Cool!!! I know they do special "Members Only" versions of new exhibits at S&I, so I'm thinking the Field will be the same way. It will be really nice if it's anything like the one we went to in the past, even with lots of members there, it still feels like you have the place to yourself. KWIM? The last time we did that was when the Titanic was there.
The dinorama in the exhibit is really neat. I also liked the computer screen they had where it does an overlay from bone to skin a dinosaur.

I don't know if you can do audio tour with the members only thing but DS & I really liked having the audio tour. I suppose I could have read all the signs at the exhibits and it would have done the same thing but I know DS too well & it was better to have oral stuff. There are a few videos in there that we didn't chose to sit and watch the entire thing of it. We spent about an hour or so in the exhibit.
Honestly, I really don't like the Field museum in general. It's just not my thing. However, DS likes the Dinosaurs and with the new exhibit it was perfect for him. Since DD doesn't like the Field either, it's not somewhere we would chose to go as a family.
Now S&I on the other hand, we all like. I'm planning on getting a membership soon. We will get the PhD one just because of us having a larger family & last time we did that we had relatives visiting but we ended up loving it. Free parking, free Omnimax tickets, etc... There are 2 exhibits coming up this year that we want to see CSI and the Star Wars one. DD really wants to see the CSI one and I think everyone will like the Star Wars one.
Have you gone to the Toymaker 3000 exhibit? I assume it's still there.

Last time we were there, they had told us about it in the member only night since you got to talk to people who make up exhibits. The kids were so excited to see it, we went when it was supposed to be open but there was a delay in the opening & our membership expired before it actually opened. We never did get to it. I'm just wondering how it turned out? It sounded pretty neat. I know the idea was that you could make some choices to have a top made that you could purchase & you could watch it being made. I don't know if that is how it ended up in reality.
