What great pictures! I was impressed that your little girl was not scared to interact with the characters, and hugged and had her picture taken with so many. Mine would hide behind my leg!
Since I live here and my (ex) husband works for the Mouse, I have been there PLENTY of times. (Tickets were part of my divorce agreement!) The schools use the theme parks for educational field trips, so the children are always going to Sea World or Epcot. I love Epcot. Once I got into Epcot just to hear Rosemary Clooney sing. I was only there two hours, but it was worth "wasting" a ticket to see her.
I've gone and had good times, and bad. It depends on health and weather and time of year (crowds). One year, I had an abcessed wisdom tooth. Not good. One year, we stayed until the park closed and most of the people were gone, so we rode Thunder Mountain six times in a row. That was good. It was also fun when (I was married) to use his pass, which gets in 6 people at a time. If there were just two of us, we would find four more people who were in line buying tickets to come in with us for free. My sister and I would sit on the benches like queens and scout out who we though was "worthy." We tried to pick people who didn't look like they were rich. (I don't have access to THAT pass anymore, unfortunately!)
I've also done annual passes at Sea World and Universal Studios, when they run a special where you buy a ticket, and it's good for unlimited park access for the rest of the year. Disney doesn't do that. My daughter has an annual pass from Busch Gardens right now, same deal.
