Man up everyone and wait in the lines!!!!!
People should definitely do the right thing and not cheat the system. Which is actually cheating their fellow guests, not the Disney corp.
But we should keep in mind that some of their motivation for cheating the system derives from Disney having attracted larger and larger numbers of customers, charging them larger and larger amounts of money, but not building anywhere near enough new attractions in order to keep up with the larger crowds spending even larger chunks of their hard-earned.
For every new attraction that has been added there has been another one closed down, made seasonal, or else allowed to lapse into what many people would consider tired staleness, to the point where return guests rarely experience them any more. Been to Flights of Wonder lately? Country Bears?
The FP+ system is in some ways an elaborate attempt to disguise the inadequacy of the Disney experience compared to 10 or 20 years ago, from the point of view of availability of rides, novelty of attractions, length of wait times, degree of crowding, and cost.
The urge to cheat the system is partly due to a tendency for people to try to out-think and exploit any complicated system or puzzle, and partly a reaction to the massive crowds, high prices and relative lack of new, interesting and thrilling rides with which to occupy their families.
