Be aware that the line to the Monorail can take quite a long time, and walking to the DLH may be your quicker option. When we were there, I overheard the CMs saying that because of the new monorails, they are limiting the passengers to 15 per car. They also take time to make sure each car has the limit and try to fill when necessary.
When we took the Monorail from Tomorrowland back to the DLH in the evening, we stood in line for a few cycles of monorails. We weren't in a hurry and enjoyed watching the Nemo subs.
