Hello, Kelly!
Thanks for stopping by planDisney. It's a pleasure to help you today. I have great news to start this answer, so let's get to it!
The upcharge for a
Park Hopper ticket is a standard fee that won't change if you apply it towards multiple days or a single day. Since that's the case, getting Park Hoppers for your trip is a much better deal than getting a Park Hopper for a day or two. I love that about the Disneyland Resort, and my husband and I usually advise our friends to buy Park Hoppers for their trips.
We simply love to go back and forth between the theme parks for attractions, entertainment, and food. This deal is even sweeter now that the
Disneyland Mobile App helps you book attractions with
Genie+ on both parks!
The best tool to know about shows and special events at the Disneyland Resort is the calendar you already know about (congrats on your excellent resEARch skills!). So my best suggestion is to keep checking back until the first week of January is included in the
Entertainment Schedule.
I love to visit the Disneyland Resort in January, and I hope you have a wonderful time there, Kelly!
May the magic be with you,
Julie
