Hi Jaclyn, welcome to planDisney!
Thanks so much for bringing your question to us, I'm here to help!
The park hopper add-on when purchasing your
theme park tickets is a one-time fee of $60 (prices subject to change) per ticket, and the park hopping option gets applied to all of the days of your three-day ticket! So to be clear, if you are purchasing a three-day ticket, you would just pay one flat fee of $60 for your ticket, NOT $60 for each day. The park hopper add-on is a FANTASTIC option, and it becomes especially worth it when purchasing multi-day tickets. I highly recommend it!
Also, I do want to mention the
Disney Genie+ service add-on. Genie+ allows you to skip the standby lines for most attractions and use the
Lightning Lane entrances, which typically results in time savings! Currently, the cost is $20 per day per ticket (prices subject to change), so the cost would be $60 for a three-day ticket. My family and I always purchase Genie+. We have two little kiddos, and we found the time savings to be a MUST!

See ya real soon!
