I do WDW solo often (I only live an hour away). It is not too bad, at least you dont have to check with anyone to see if they want to ride this ride or go to this park.....etc.
They also have parades of the stars and interviews so you will get some good pictures there too. Also, you can walk around the autograph areas and get good pictures. Faith and I seem like we go around in circles all day but it is fun looking for the stars.
Also.....good place to see them being moved from place to place is right at the Star Tours area, between that place and the counter service place is a gate that they move the stars in and out of all day. You will see lots of people hanging around there.
Faith and I are supposed to be staying at the Swan also - as long as she is able to make it. If she cant then I may have to find a place offsite but I will definately be there!
If you want to meet up let one of us know. I can give you my cell number if you would like. I know you will enjoy the day. Oh and I would recommend seeing the Street Jam. I watched it for the first time last year and enjoyed it - I watched it on Sunday and it seemed less crowded than on Saturday.
