I would say probably not just given the monorail has the potential to be pretty full when it gets to CR.
Just a one moment in time example, but last year at a mid/late Sept party we left just after midnight heading back to GF. Express monorail was closed (either intentionally or due to closure, I’m not sure), so all monorail traffic was routed to the Resort line. Line was long. GF/Poly boat line was really long too. I flipped a coin and chose monorail, which was a bad idea. While the boat line was super long (longest I have ever seen), several came in a row (including a big one) which churned through the people in line relatively quickly. I sat and watched crammed in the Resort monorail line kicking myself for my decision.
So, for Poly I’d either GF/Poly/MK boat, or the Ferry Boat to the TTC and just walk.
