Amazing opportunity to see the control room and scientists researching. Our tour guide was brilliant and very informative, she knew the answers to all of our questions! We also got to see the radio telescope from a viewing platform.

It’s a great trip to take with the kids they will learn some fun facts they can probably use in school and they can see the largest satellite in the world .( Excused the pictures it rained on this day but still worth the trip)

I didn't make a reservation, I bought the tickets on site. I am not sure of how crowded it may be during the holiday. I recommend you call them, they will help you.
