Based on previous experiences over the years, that should be a pretty decent time to visit - a couple weeks after the marathon/runs, after MLK weekend, and before the mid-Feb pickup with Presidents Day/Valen Day/Daytona, and sometimes Mardi Gras. Being there on a Thursday will help. It's a time we really enjoy going, especially in recent years with the Arts Festival. We have yet to be there when GOTG is open, so no personal experience with that - but we have done VQs in the past that have worked well for us. So you'll probably want to consider the VQ (or ILL), and possibly G+ for Ratatouille. All things considered, your date for the day at EPCOT is probably a decent option with regard to crowds. That said, crowd predictions since Covid have been much more difficult to grasp sometimes! But late Jan can be a great time to enjoy a day and/or evening at EPCOT, with no heat, and with our favorite of the festivals..... Enjoy!
