I started my trip in California Adventure and believe me, it's so weird seeing the Paradise Pier bay all drained and looking like a skate park. The scaffolding of the Sun Wheel makes me sad too because I love that ride but I'm looking forward to seeing the Sun Wheel. The park looked absolutely amazing all decorated for the holidays, especially the Golden Gate Bridge. I stayed there up until the sun went down before we made our transition to Disneyland.
Once we were in Disneyland, everything was lit up and it was great seeing the Christmas tree and the lights down Main Street. The one particular part I didn't want to leave was New Orleans Square because everything was so beautiful lit up. We had fun going through Fantasyland and getting a glimpse of the castle with the lights on. Also, we were right behind Dumbo when the fireworks went on, getting the most perfect view ever even if we had to go from left to right with fireworks going on both sides. I did get caught in the "snow" by the It's A Small World area and I only got one picture of the ride lit up since there was a huge crowd. After that, I had very little battery juice so I got a few pictures of Main Street, only uploading one into my Flickr for the time being.
I will be going again this Saturday while we go renew our AP so I'm looking forward to adding more pictures even if I have to wait for the first of next month to upload again.
