I’m visiting 11/26/21. Due to the new Covid outbreak, I hesitate buying advance tickets. If museum is open that day, will I be able to buy the tickets when I arrive?

I went labor day weekend and it was surprisingly not busy

Yes you can

We were there in August and did purchase ahead of time but the employees working there did they've never seen it this slow. I thought there were a lot of people but apparently cause of covid they're slow. But I did see a lot of people buying their tickets and just waited in a short line. In advance you do get to walk right through which was nice.

Yes you can buy it when you arrive. The line was not to long and I went with my family on Saturday.

You can just buy them the day before to avoid the lines.

I was just there this past weekend and there was a long line to get in. Same day tickets

Yes, you will.

My friend was able to buy two tickets at the memorial the same day we visited with very little wait. It was a Thursday.

I believe you can, however I purchased tickets in advance and was able to walk to the front of the line
