Brian,
Having been to WDW several times solo, I can tell you it's a blast. Some people don't understand how can people go solo. I've heard all the remarks: how could you go solo? Won't you be lonely? Isn't that a little selfish? And so on. Well, I tell them that I do go with family and have a great time, but there are times where our schedules don't match and I end up going solo and have a great time too. You get to do what you want, when you want, go where you want, dine where and when you want . When I went last November/December I was supposed to stay at Caribbean Beach, but since it was closed, I got upgraded to the Polynesian. I had planned each day out ahead of time, made ps arrangements, etc. and I usually following these plans, but for some reason this trip was a little different. I kept some of the PS, but ended up splitting the day into 2 and sometimes 3 parks. I would go to the EE park first thing, spend the morning, leave around lunchtime, head back to my resort for a break, then later on head for another park. I found that breaking up the day, kept things refreshing.
When I go solo, I ALWAYS stay on-property for many reasons. I never rent a car, since I don't leave WDW, so by staying in a Disney resort, I use the boats, monorail & buses to get everywhere. I also use common sense while I'm at WDW, both in the parks and at the resort. I always double lock my room door, even if I'm only going to be a minute. I also make sure I am secure in my surroundings. I never take too much money with me to the parks. Usually a little cash & my room key. Less to lose. I usually bring a book with me too. It breaks up the time while waiting for a show to start, while standing in line or while dining. I find that the CM's are very friendly when they notice you are solo. Make sure you take advantage of the single's line on Test Track. MUCH MUCH faster than the fast pass or regular line. Road it 5 times in a row on my last trip. I found myself taking more time to absorb the parks and the architecture. At AK for instance, I took a nice quiet walk around the Tree of Life looking at all of the animals carved into it. Most people don't bother and it is a really quiet walk and you can hear the soft music in the background. Another solo plus is being able to dine where and when you want. This past trip I had the chance to try several new places. When you go with young nephews and nieces, it's great, but they really don't want to sit for long durations, unless there are characters around. You've got to try Spoodle's at the Boardwalk. VERY GOOD!!! I found wandering around the parks is fun. I also found alot of people tend to strike up a quick conversation while waiting in lines or for a show.
Where are you staying? When are you going? If you have any questions, drop me a line!
HAVE FUN!!!!
