We attended our 1st party last night and I enjoyed it very much. I did not get to do many special party things since we had our 4 year old with us and my DH isn't a Disney person like I am. But we still had fun.
The park did not feel crowded to me at all, but I'm used to summer crowds. It was warm, I was in shorts and a tank top, and we had a few sprinkles around 5p.
We caught the Castle Lighting, fireworks and last parade. My mom, son and I got our spot next to the steamboat about 5 minutes before the parade started. We were not sitting and not front row, but there was an open spot where we could see quite well and get some pictures. My son fell asleep in the stroller as soon as we stopped moving, which made enjoying the parade a little easier
He wanted to ride rides, so we did. We even managed Peter Pan and although posted wait time was 30 minutes, we were off the ride in 20. Most of the other rides we did were 10 minutes at most, usually less than 5. We did not do any of the Mountains or 7 Dwarfs during the party. My mom managed to snap a picture of the Dwarfs by themselves in between people! Took her 2 tries. The princesses/princes had a 60-75 minute wait the 2-3 times we walked by.
I loved the parade and the snow on Main Street was cool to see!
