I'm definitely fine with any available option. I may end up with 40+ people in the park with me during MHP. so this is an exciting challenge for us to try to capture everybody. I have 2-man camera crew including myself, and will additionally use any photopass manpower I can get, if that's available.
Also I'm certainly not trying to hijack the thread, just expanding on it. The train cars were my first choice - and I'm happy to hear that it's at least available for photos.
Mark Twain sounds spectacular and would be the most stunning.. that 19th century look at nighttime would be amazing. It would look like our own private cruise. Of course, with my luck that's going to be closed also.. Any picture opportunities would be great...
As far as movement + group photo/video, I'll have to look at Jungle Cruise.
The horse-drawn car is another strong wish, but I'm imagining it won't be available during MHP.
There is also a sequence in Haunted mansion where you can see 10+ carriages all facing each other in a semi-circle array. I plan to get that by taking the the last carriage in the group.
