Let us know how it goes! I highly suggest EPCOT when Solo, but I like to shop, sip and eat all while just strolling and taking it in. When I am down there for the winter I am often solo as my kids are older and work and my husband is at work. If the ride lines are low, I will always hop in and I can easily spend the day there just taking pics and enjoying!
If I am just choosing a park for rides, I do the Studios, because there is so much to see and do and ride there and still a few places to wind down.
Enjoy!
