A very quick word about FP: the perceived FP issue depends on OPERATIONS and whether or not an attraction is an omnimover. Math and data work only in a theoretical universe where Disney isn’t trying to artificially create lines to hold guests in place. And they are.
Before FP+, many attractions had two queues that kept the standby lines moving quickly (e.g. POTC). Others merged before a split (Space Mt.).
Post NextGen, those attractions now hold guests in a standby queue even if nobody is on the FP side. Pirates is the most glaring example, but it happens at other attractions too. This cuts the loading process in half, with half the dock empty while Guests are backed up in standby. Sometimes BTMRR gets around this by operating only one loading dock; it saves staff $$$ but creates an artificially long wait time on an otherwise slow day. At Space Mt., FP is usually sent to the right track while Standby wraps through the left switchbacks. In the past, the merge point came at the top of the star tunnel, and the switchbacks moved quickly. Guests are punished for using standby.
High-capacity attractions such as SSE, IASW, and HM — and less popular ones like Imagination — have unnecessary lines because Guests pick up unneeded FPs in the MDE app, and constantly slow down a loading process that was designed to eat crowds.
The big issue is that Ops doesn’t use load capacity past the merge point.
