Karen,
Smart thinking about the Park Hopper. Use it as needed, not simply because you have it.
Here is what I would do, assuming that you are not visiting parks on arrival and departure days;
- January 24 - Magic Kingdom (PM Extra Magic Hours)
- January 25 - Hollywood Studios (PM Extra Magic Hours)
- January 26 - Epcot (AM Extra Magic Hours)
- January 27 - Animal Kingdom (PM Extra Magic Hours)
- January 28 - Magic Kingdom (AM Extra Magic Hours)
- January 29 - Epcot (PM Extra Magic Hours)
I doubled up your time at the Magic Kingdom because there is more to do there than any other park. I also have you doubled at Epcot due to Extra Magic Hours, though that may be a mistake. If you have younger kids, consider spending the afternoon/evening of the 26th at the Magic Kingdom to get more time there. If you have older kids, think about visiting Hollywood Studios on the morning of the 29th.
Write me back with more about your party, your park time availability on the 23rd or 30th, what you like/don't like about this schedule, and we can tweak this a bit.
Have a magical vacation!
