Wizards of the Coast modules - Do I need the physical book?

I'm terribly sorry if this has already been answered, but I did spend time doing searches to try to find if it had already been answered. Perhaps it was asked another way... In any case I'm wondering if I need a physical copy of the book in order to run a WotC module that I purchase here on Roll20. Specifically 'Princes of the Apocalypse' if it's different for each adventure module.

Hi Jeff. Everything in the book is included in the Roll20 module. You'll have all of the maps laid out in the pages toolbar and the entirety of the text of the book will be in handouts in the journal. In addition, you'll also have handouts with every image provided in the book and fully statted monsters and npcs. I've got several of the modules and I can't reccomend them highly enough!

Thank you very much for the information Kirsty! This site is so awesome!!

No problem, Jeff! If you'd like to have a look-see, I'd be happy to invite you into one of my games. I don't have Princes (I was already running it when the module came out, though I'm considering buying it just to same myself time) but I've got several other ones. They layout is pretty much the same in all of the modules. :)

I wasn't expecting an offer like that at all! I would have happily accepted if someone else with pota didn't message me as well. Thanks again for showing me the wonders of the community. If they don't follow through I won't forget your offer. :)
