I've been thinking about how great it would be to be able to build a ride where you could go over and under other parts of a ride or a room, then it hit me...there appears to be a new ride piece, the entrance to some of the rides where there is a gate AND A ROOF OVER THE GATE.
Stay with me...it might be possible to put ride pieces OVER the entrance...like, right on top of it, which means, you could start building rooms where you enter right near the start point, then could use the entire room! Anytime you wanted to be able to walk under the ride or walk under some part of the room, just put one of those pieces! It would act like an arch (something I've been wondering why they haven't included) and let you build more than one level to each room!
Let's hope you CAN put something on top of that piece so this is possible...if you can't then I'm getting excited about possibilities that don't really exist!
