Only going to be in Seattle one day, want to buy tickets in advance for Space Needle on Sept. 14th, 2018, but can not pick time slot because of flight, car rental and light rail time to arrive downtown. If I pick a time slot is it flexible?

Hi Huey. If you were to book a time slot for the Space Needle and miss that time, you will then join the queue with everyone else who did not book in advance. One thing to consider is waiting until you are in Seattle to book a time slot -- there are typically times available even day of! And yes, the Space Needle just underwent a multi-million dollar renovation. Construction has been completed and the result is stunning!

Not sure but i was very disappointed just check if the needle is 100% open the tower was under construction they charge full price yet we could only see out from 1/4 of the viewing deck the rest was under construction absolute waste of money.
