Epic will probably start out strong, even if they abuse the AP's...BUT, Studios and IOA will probably see a significant drop in attendance if they abuse AP's. And once someone leaves as an AP, good luck on getting them back. Universal still doesn't have the 'branding power' that WDW has, and they rely on Floridians for much of their attendance, which is really evident on almost always very crowded Studios and IOA on weekends. Universal will be playing Russian Roulette if they don't try to accommodate AP's after the first couple opening months. If they offer AP's discounted passes, as
@GAcoaster has suggested, that will soften the blow initially. But that kind of goodwill will only work for a short time. Meantime, Studios and IOA really have no significant new offerings to entice local guests or tourists. Return of a night show and parade help, but a few years old Velocicoaster is really the last D/E ticket sitting out there in those two parks.
