I was also there today. I'll probably write more later when I actually get home, but here are a few notes:
The new train car looks a lot better than I was expecting based on the first reviews. It sticks out a little, and it seems a little less quaint than the old style, but it's not bad at all.
The park was packed to the gills today around 5-6, lines were so bad I spent most of that time just wandering around. However, it really petered out after the first light parade and by 8 the lines were getting fairly short on everything.
Man, the prices keep rising. A bottle of sasparilla is now $2.60 for some reason. I don't know why they felt they needed and extra 10 cents halfway through the season. All the other prices were noticeably higher too...
I didn't ride the train till dark, and I couldn't see much from TGS or from the gate nearby, but I did spot one marker that was almost directly on the train tracks on the other side from the old cabin. I'll ride the train tomorrow in the daylight and try to spot more and get some photos.
Pretty good day all around, headed back for more tomorrow.
