Not against upcharge express options since Universal has shown it could work when your park has multiple high capacity attractions and limit the amount sold.
With that said, standby queues need to change. Always been a fan of the Fallon queue where you are allowed to roam an area, sit down and relax before getting called up into a smaller queue prior to boarding/preshow. Imagine if on Hagrid's you can explore an actual forest where you try to find different creatures, relax inside a cave with seating/chargers, before getting called up and checking in to "class". Or exploring the Hollywood Tower Hotel grounds before being called up for a "library/hotel tour". Heck, add a small gift shop while guests wait. (Obviously this could be turned off whenever queues are short, just like Fallon)
