I've read some reports stating the monorail is again running in a loop? Where are all of its drop-offs and pick-ups? i.e. can you pick it up in Tomorrowland, ride it to DLH for lunch/dinner, and then get back on to go back in to DL again?
The monorail still has the same two stations, Tomorrowland and DTD. It was only running half of the loop for a while, and you would have to exit once you got to either destination. Now, it is running the full loop and I believe you can stay on and get off at the place where you got on (ride the full loop).
So, to answer your question, yes, you can ride it from TL to DTD and eat dinner at the DLH, then catch it back into the park after you are done.
