Tickets - You can buy your tickets online and save $2 on each one. With your ticket, each person gets 3 tokens (it used to be 4). The tokens are for some of the more popular items, like the modeling clay and making your own marker. They discontinued giving the empty box that you filled with crayons at stations throughout the building.
Parking - There is metered parking around the museum. I found parking there every time we have gone, but we always go early in the day. Their website also lists parking options.
There is also a list on their website of restaurants that are close by.
First Floor - The gift shop is an obvious favorite. This it's new location, instead of it previous one a few stores away. It is a Crayola wonderland and the kids didn't know where to look first. One of the really interesting options is the huge wall of rare of discontinued crayon and markers. You can purchase an empty tin and then fill it with your choices of markers or crayons from that wall.
Second Floor - There are lots of options on this floor, but the kids' favorites were making your own marker and the modeling clay.
There were three color choices for the markers and the kids got to watch it being made.
purchase additional packages and accessories. The tables are stocked with cookie cutters and other tools. There are markers also available. We learned on a previous trip that you can color on the clay.
Suggestion: Bring a Ziploc bag to keep the clay soft and re-usable if, hypothetically, your son wants to move on to the next exhibit because his sister is taking soooo long with the clay.
The water exhibit is still there, but it was remodeled with a Crayola theme
instead of the previous canal one. The line for that was very long all day, so we did not do that this time.
Fourth Floor - "The Melt Stuff Floor" . There is an exhibit where you can melt crayons and make a type of spin-art. At the Melt and Mold exhibit, the kids melted crayons into new shapes. The day we went, the options were a "Crayola Guy", a dinosaur or a ring.
