Export entire Map Series to a single PDF

[Lake_Worth_BeachAdmin]

I have a map series that has over 50+ pages. I know I can export each one individually to a PDF but this is very time consuming. 

is there a way to export the entire series all at once? Ideally to a single pdf but if multiple PDF's that's fine I can merge them in Adobe.

Q: How do I export all pages within a map series at once?

I export the pages as a single PDF file and my exported PDF contains the 11 pages:
