Hi, can we buy tickets inside the museum ? or do we have to buy online ?

You can also do Groupon. We paid $16 for 2 tickets.

You can buy tickets at the museum just inside the entrance.

Yes, you can purchase tickets inside the Museum or online in advance. Please visit our website for hours of operation and days we are closed. Here is where you can purchase online: https://www.navysealmuseum.org/tickets

Thanks you Travis for the answer !
