Hi Cathy, welcome to planDisney!
Thanks so much for bringing your question to us, I'm happy to help!
My family and I are huge fans of the
park hopper tickets. Currently, the park hopper add-on costs $60 per ticket (prices subject to change). It is a one-time fee, and if you purchase a multi-day ticket, you will just pay the $60 fee (prices subject to change) once, and the park hopper feature would get added to all of your ticket days. So, for your situation, if you purchase a three day ticket, and add the park hopper add-on, you would pay the $60 fee, and the park hopper feature would be added to all three days! Very worth it in my opinion!
And great choice on deciding to purchase the new
Disney Genie+ Service add-on! My family and I are huge fans of Genie+ as it allows you to access the
Lightning Lane entrances for certain attractions, which should help you avoid the standby lines and save time! And another great perk about Genie+ is that you get unlimited
Disney PhotoPass Digital Downloads with the purchase of Genie+! Awesome right?
