Yes. Try going in the night. Easier to find parking and very less crowd.
Yes!! Tickets are required and sell out in advance.
Yes, you will need to purchase a ticket online beforehand, which means you will choose a time to go. Buy FLEX tix, and get the most of your time as you have more leeway.
The exhibit is in just one room and the images are displayed on the walls and floors. There are defined spots for the patrons to occupy so that means there are limitations to how many people can view the exhibit. If you buy a Flex ticket, it gives you a four hour window (+ or - 2 hours from your ticket's time) otherwise you should be there at the time of your reservation.
We bought flex tickets, MUCH EASIER, so you need not arrive at an exact time.
You need to buy tickets, and the tickets are scheduled for specific time slots. So yes you need reservations.
