I love going to WDW with our family and Epcot is fun for adults. It's a great park for wandering around and seeing all the nooks and crannies. It's very relaxing and beautiful. You can buy tickets at the hotel or the entrance. I was there last September with my daughter and 5 grandchildren. Even if you don't ride anything, they have lots of almost spontaneous sidewalk shows from different countries singing, doing acrobatics, or other things. You won't feel funny being alone. Good luck!
