I think the real problem about the buses is that they just aren't predictable
- and that applies to ALL Disney resorts, not just Port Orleans. Most of the time they work just fine, but sometimes (such as this one) the whole system can go horribly wrong for no readily explained reason (although everyone running out of the park to avoid a storm would put pressure on any bus system). I guess we probably tend to notice more posts at the bad end of the spectrum though, as people tend not to bother writing special posts saying that they got on a bus and then arrived at the park 10 minutes later.
From my own experience of 20+ years of using Disney buses from Port Orleans I can honestly say that I personally
have never experienced any real horror stories such as the above post. For the last five or six trips I've logged every trip I make, with wait and pickup times noted, and nothing has even been outside of the intended maximum 20 minute window apart from a few post-fireworks return trips (although I mostly try to avoid that time anyway, so my logs might be biased).
Actually, one time that I did use the after-fireworks bus service, this was the queue for MK bus stop #28 on 1st Sept 2015 when I arrived at 10:55pm!
However three buses arrived in pretty quick succession and ate up all that queue very fast. After less than 15 mins waiting, I got on a bus at 11:09pm and It departed from the MK at 11:11. It dropped off at West at 11:24, North at 11:26, East at 11:29 and finally South at 11:32.
I can't get my head around the new routing though, with ALL of the park buses doing the circle route first when most people use the South Depot. I guess it helps for those who want to use the outlying stops who might otherwise see mostly full buses, but surely it just makes the queues worse at the South Depot?
