FAIR WARNING!!!! once you go solo you won't be able to stop. i finally took the plunge and went. (check out my solo trip report below). i had alot of fun. it was scary at times as i am very shy but i had a great time. i took the keys to the kingdom tour which help me come out of my shell a little bit and talk it up with other people. i did some times feel like i avoided eating at places where i thought i would get stares. not so...believe me, people don't care as much as we think they do. at disney i only did counter service places but finally did table service places at my solo universal trip.
as for disney, the only drawback was after a few days, i was getting lonely for company and felt like i would die if i didn't talk to someone soon. but it worked out in the end. i did what i wanted to when i wanted to. that is the biggest plus. the only time that i felt a little sad (missing my family) was at the parade and wishes fireworks. made me a little teary but now that i think about it...it always makes me teary. go..........you will have a great time!
