Hello there Charlotte,
Welcome to planDisney and thank you for your question! It sounds like you're planning a trip to the Happiest Place on Earth at the beginning of next year - how exciting!
My suggestion on how many days to visit the Disneyland Resort really depends on how you like to
vacation. Typically, when I visit with my family, we go for 3 days. We like to purchase the
Park Hopper option for our tickets so we can hop between the two parks each day starting at 11:00 AM and we also purchase
Lightning Lane Multi Pass so that we can access the quicker Lightning Lane queues. Both of these options give us quite a bit of flexibility during our visit so that we can fit everything into those 3 days that we'd like.
If you like to slow your pace down, take your time, and maybe even have an afternoon break or two then I would recommend looking at
4- or 5-day stays. Adding in these extra days will most definitely make sure that you can experience everything that you'd like to do during your visit.
In my opinion, 1- or 2-day stays typically feel too short or rushed - especially if you don't visit the Disneyland Resort very often. From what I've found, that 3-4 day time period is the sweet spot.
Thanks again for your question, Charlotte! Make sure to come back and see us if you think of any follow-ups. We'd love to help!
Have a Magical Day,
Greg
