I think that the long waits for the 7DMT are a result of low capacity and the fact that WDW just needs more E-Tickets (and more C and D tickets) for WDW's immense popularity and the money that they're bringing in. If WDW had a proper number of rides with proper capacity, 7DMT would a pleasant break, but nothing too special.This thread is funny.
People are arguing that it isn't high enough capacity and at the same time say it's a mediocre ride. The ride is 5 years old and always has a line, that would be a successful ride by any ones standards. Doesn't matter if you like it, it matters if the average MK guest likes it. They do. Word of mouth must be good as well. How's the new Star Wars ride turning out? Brand new and rumor has it 7DMT has longer waits?
I also find it funny that the OP starts off by saying the mine train is a family ride then goes on to say he is annoyed at all the children and the childish stuff in line.....That's pretty much like going to an old folks home and complaining about how old the people are there. What did you expect?
I just thought of something, I have never ridden the mine train during the day. As far as night time it is a good family coaster, it could be longer but it's good family coaster and that's what it is meant to be. It's very smooth with Grandma and 5 year olds all riding it no problems. That is not true with intense roller coasters. I don't see Granny on Everest or RnR.
