Those who had hoped to see the ancient artifacts but never got around to it should also move fast, because King Tut will be leaving Seattle in a matter of days.
Olympia residents Marla Fralin and her family bought tickets to the exhibit months ago.
"Because we knew that it would be ending and it was the last time it was touring," she said.
Science Center CEO Bryce Seidl said the Tut exhibit was an unmitigated success, even if it didn't make the center rich.
"The Science Center doesn't make a lot of money on the exhibition," he said.
The exhibit generated more than $15 million, but the majority of that money goes directly to Egypt.
Those waiting for the next big exhibit to come through town will have to wait a long while, according to Seidl.
"There is no other exhibit of the magnitude of this in the world today," he said.
When the exhibit closes for good on Sunday night, the giant hall that has housed it for months will sit empty.
Tickets are sold out through the weekend, though there are still a few available on websites such as Craigslist. Despite the high demand for tickets, people like Fralin wouldn't give up their chance to witness history for anything.
"The artisanship and craftsmanship of all the artifacts are brilliant," she said.
Some experts say because of the political turmoil in Egypt, once the artifacts return home they may never leave the country again.
