what are the differences between the cars, coach, vip,and dome. wondering if it is worth the money to upgrade.
For us, the dome car was the way to go. The view from the dome is so much better than the regular lower coaches.
When we went, it was just a train ride (no theater) and the price was the same for all the cars. Some cars had a/c and a second "floor", which I didn't care for because it's very skinny and it's just a long bench. The main "floor" has regular train seats. There were other cars without a/c where you could open the windows. And there was a car where they sold snacks, but we didn't visit it. Never saw the different options that you mention.
We rode in an open car because the weather was pleasant, and because it allowed me to take pictures without a glass pane being in the way. The other cars were closer (but not much) to the amenities, and some of those cars were air conditioned. Since we did not explore the other cars, I cannot advise further.
