If the Imagineers bothered to think it through, every E-ticket, even the thrill rides, could have 2,500-3,000/hr. Soarin' should have had 4 theaters from its opening day. TSMM should have been built with 4 tracks or higher-capacity vehicles from its opening day. RnRC should have been designed to fit 4 per row instead of 2. Same goes for SDMT. Test Track ought to have 4 rows of 4 like DINOSAUR. Peter Pan should have been reworked to fit 4 per boat a long time ago. So many missed opportunities to increase hourly capacity if they had just bothered to go that extra mile.
Star Tours and DINOSAUR are proof that TDO is capable of designed relatively high-capacity Es (Star Tours and DINOSAUR never go above 30-35 minutes even during the FP+ era from my experience... then again, I've never done Star Wars Weekends or Christmas time)
If every E-ticket had 2,500-3,000/hr, you could experience far more in a day and enjoy your visit leisurely. But when you've got 75+ minute waits for some of the big attractions during peak season, you either have to skip it or luck out with a FP+ reservation.
