I can see that, just throw all the attractions into one ride category and make people pay to book more than one from that category, because... hey, why not...
They can make tiered levels of the fastpasses you pay for! They have the CL 90 day ones, a normal 60 day one with multiple from the same tier... and the sad thing about something like that is I would pay for it because I would rather enjoy my time making memories instead of standing in lines. I don't have fond memories of waiting for things... (I also have 2 younger kids that don't do well sitting around)
They're pushing in this direction, CL fastpasses aren't subject to these restrictions, only the (would you call them complementary?) fastpasses.
