Here is a tip for you when you visit. Don’t stand in the line outside to get the tickets for the planetarium show. There are computerized terminals inside for you to buy the tickets with a credit card. One is at the west end of the new area downstairs, by the Café At the End of the Universe. Get there by entering the new west entrance, going down the stairs. There are others but I never saw them. It’s silly to wait outside in that long line when you can go right in and do it that way. I was in the line, and my wife and brother were inside and found the terminals. I was in the line for 15 minutes before my wife came out and got me. Also when it comes time to go to the show you need to go to the East end of the main hall and go out the door to the south and get in the line. Great show! Well worth it.
