Hi Amy!
You're welcome!! It is my pleasure to help you.
Good news, there actually IS a one-day PARK HOPPER option available. I was just playing around on the Walt Disney World website and was able to do this. First, log on to
www.waltdisneyworld.com and then click on "Parks and Tickets" at the top of the top of the page. From there, click on "Theme Park Tickets" from the drop-down menu. Once you get to this page, you will be able to select and customize the number and type of tickets you need. A one-day, park hopper ticket is the most expensive per day...$89 plus tax PLUS $35 for the "hopper option", but if that is all you need, then you can do it.
The premise here is that the longer you stay, the less expensive it is per day, and also per option. For example, the one day prices above become $64 per park day, plus $14.24 per day to add the "hopper option", but obviously, these cheaper options only make sense if you have the time.
The good news is that if you only need the one day ticket, and want to "hop", you can! Please let me know if there is anything else I can do to help you plan.
I hope this helps and I wish you a Magical trip!! :)
