If I purchase my tickets from Groupon, will I just show my phone with proof of purchase. I have read the comments from previous years, but I want to make sure that it's the same this year

I bought my tickets on Groupon and had no problem. I saved and screenshot them. They just have to scan it.

Yes. I have been fine with them scanning my phone. However, have them saved on your phone in case you have a bad connection to the internet on your phone at the gate.

They'll scan your phone and you'll be able to enjoy all of the festivities. Get a turkey leg for me!

Yes, agree. Reception out there can be questionable aft times but they will honor Groupon tickets this year(2020) as they have before.
