I bought a season pass for my granddaughter online. It is a Christmas present. Will I receive anything in the mail with the Dorney Park logo on it stating that I purchased this?

U should receive a email instead

No. You should receive a email statement with your purchase

It's best to specify ahead of committing to the purchase but contacting the parks help office can get you info on how they are packaging mail order tickets for the holiday season. Lots of vendors ship in plain packaging for the holiday with the knowledge that the item can be a gift.

You can contact park services ... You should be able to print something

I would go online and get a printout of your purchase.
