Yes, I did have such a wonderful time and I was a bit surprised by it.  Next time, I go solo I will have to give myself at least a week so I have time for everything.  There was just so much I did not have time to see.  I loved the tours, but they ate a lot of my time away. (but, I would do them again in a minute!)  I also think the tours are a great idea when traveling alone.  
GoofyinOhio:  The only time I felt I had no one to talk to was when I got back to my room at night.  So, that's when I usually called home to see how everything was going.  It made me feel a bit more connected.  I felt the hardest part was dining alone in the nicer resturants.  I just felt just a bit alone, but I definitely could do it again.  
Bostoncq:  I had no problem striking up conversations.  In fact, a lot of people started talking to me because they saw that I was alone.  Most people are so friendly while at Disney.  I also think that a lot of people want to talk to other visitors to see where they are from and what they do, etc.  I must admit that the people who took the Backstage Magic tour were really friendly and a lot of fun.  The people on the Keys to the Kingdom tour were not.  Truth was by Wednesday I no longer care as much because I was feeling comfortable about being solo and I was seated with the CM for lunch so I had someone to talk to.  
Horizons1 -  You are right,  Magic Express was definitely anything but magical!  I have never rented a car before.  I always felt that I did not want to get lost in WDW at night.  I hate night driving and did not want to have the stress of driving while I was on vacation.  Is it hard to get around WDW when driving?  When we go as a family in November, it may make more sense to have a car.  My brother will never be able to handle a whole day in the parks and we do plan to visit Sea World, plus I know my brother will disappeared at least once to play golf.    

 I have never had a problem with the buses to and from the parks, but this time the wait was really bad.  Hopefully the problem will be correctd.
