Apologies for the delay, but it was quite the trip! We ended up staying a few days longer since working remotely from the resort ended up going really well. Thank you all for the recommendations! This is what I ended up doing:
Day 1:
Took the Skyliner from Pop to EPCOT and then walked to Beach club. It took me around 40 minutes in total to get from my hotel room to my destination. I went directly to the Solarium, which was a really nice, comfortable spot with a few outlets. However, there is a pool table in this room and after about 3-4 hours a father and son decided to play and I found it pretty distracting. It was time for lunch anyway, so I packed up and went looking for some lunch and another spot.
Grabbed lunch at the Marketplace and stumbled across a quiet hallway just past the Yachtman Steakhouse:
I decided to eat my lunch here and noticed there was an outlet right next to the small table! This location surprisingly didn't see much foot traffic, and it conveniently has a restroom and water bottle refill station right next to it. I ended up spending the rest of the day working here.
Day 2:
I returned to the hallway table where I spent the first 4 hours working. There was a bit more foot traffic today, but in general I had a productive morning. I grabbed a quick grab-and-go lunch from Hurricane Hanna's, but when I returned, someone was sitting at the hallway table!
Since the table was taken, I went on an adventure and managed to find the perfect place on the second floor of the Yacht Club. There is a stairwell to the side of the lobby, pictured below, that takes you to a fairly quiet nook with a full-sized desk and a decent office chair!
At first I thought the desk might be off limits, but I asked a CM in the lobby and they told me I was free to use it! I ended up working the rest of the day here and another 2 days the following week. I probably got several dozen weird looks, but I honestly couldn't have envisioned a nicer spot to work in.
A bonus of being at Beach/Yacht Club was that I was able to sneak out and meet up with my family to tap into the IG around 1pm a couple of days to snag a Guardians of the Galaxy VQ for later in the evening after I got off work.
Thank you all again for the tips and helping me have a marvelous vacation despite having to spend four days of it working
