Nic, I love Christmas Town because it does have a feeling to it that I think the park really did a great job with. As I recall they said when guests walk through the park they want them to say "Now this is Christmas" and they really delivered.
The 6-7 million lights add a lot, along with the decor. All the little touches make it what it really should be. I haven't really ridden the train ride, but I did once and it was really nice.
In my full opinion, I think I only go for the experience, the feeling, and the overall atmosphere of the park. I also think that the coasters being closed reinforce the idea that Christmas Town is not just rides like the regular season is, Christmas Town is much more.
