Thanks for your question, Ryan!
Yes, you are correct...an adult 4-day non-park-hopper ticket allows you to go to any single park, and only one park per day. You also can only use the 4 days on the ticket within 14 days from the first day of use, unless you add the "non-expiration" option.
If you want to visit more than one park, you either need two separate tickets, or you need to add the park-hopper option to your ticket. Usually it is more economical to just add the park-hopper option to your ticket, instead of buying a separate ticket.
Hope that helps!
