I was at the park all day today and only saw a very few old men riding this thing, although the trains were running almost all day long. Otherwise, the only people around were the two CM's out front with the mantra that it will open on the 28th.
It was my opinion that NOTHING was going to be happening any time soon. If there's training going on, it's sure not being done at the ride/attraction itself. There was no labor, gardening, construction, painting, etc. There was nobody that I could see anywhere other than those few on the ride or the two out front.
I do admire how quiet that train runs though. It's a whisper compared to Thunder Mountain with all it's clackity clacking that goes on with that ride. I could bare hear the 7DMT running while standing very near those trains running around.
Also, the whole set is quite attractive. The construction looks beautiful. No corners were cut in making it all look very Disney. The only thing that can compare is the Pirates ride. As I went through that queue line today I kept thinking about how well the details were done on that ride, to the point that I didn't mind the 25 minute stroll up to the boats themselves. The outside of 7DMT is like that in my opinion.
