Hey there Madeline, and welcome back to planDisney!
I ran into a similar situation for a recent family trip and had to upgrade the tier of my
1-day theme park ticket. It's definitely possible but is subject to ticket availability.
For your question submission, it looks like you indicated your arrival date is November 14, which you can use a tier 0 ticket for, but if you're looking to switch to a different arrival date then I've found the
1-day ticket FAQ page to be helpful!
In terms of making that upgrade to a tier 4 ticket, I would recommend
calling a Cast Member at the Tickets line to ask about your options. They should be able to help you with the specifics of your situation so you're ready for your visit to the Happiest Place on Earth.
You'll be arriving to the parks in the midst of the
Holiday season, and one of my favorite parts of this season is the food and beverage options! If you haven't already seen, the Disney Parks Blog recently published Foodie Guides for both
Disney Festival of Holidays and
the Holiday season in general. I love using these as a guide to find all the delicious options to try during my visits!
Thanks again for your question, Madeline. I hope you have a fantastic trip!
Have a Magical Day,
Greg
