Dude - Peace! We arent at war, so Im going to read your response as sarcasm. - cause I would hate to think it was anything else.
But - Fire Marshall would be concerned with building capacity - thats what greeters are for.
Capacity in the area/Land is a different thing since people are moving: not fighting to get up to the front of a stage to see the Rolling Stones and staying there. There are still capacity restrictions for safety reasons, but again you are holding an entire area hostage with exclusive access to two E-Ticket attractions hostage for hours to those who got into the area and may not leave to make room for others. Like it or not, the folks who make it in can stay as long as they want and in the 5 hours someone on the outside may still be waiting in line they could ride FJ, DC, etc multiple times with virtually no wait (according to DC wait times posted and single riders line for FJ). That problem balances itself out ONLY if you allow everyone the same access to the area - yeah it raises wait time for the individual attractions but everyone has the same access.
My basic point is they are creating artificial lines/crowds/waits, etc and miniscule wait times for specific attractions inside the area when the ride queues themselves should be doing the jobs they were designed to do.
Just like the beef I have with Fastpass in a lot of locations: artificial wait times and exclusitivity. Take Peter Pan in particular, Big Thunder for another. They hand out 60 percent of their daily capacity for those two attractions in Fastpasses each day because people "expect" it, and it creates an artificially high wait time in the standby line that never existed prior to Fastpass.
And obviously they are making a killing on HP already - why not strike while the irons hot and make all you can? Especially while its crowded and you can sell some new package that (since youre already operating on a 365 day schedule doesnt cost much to man and maintain comparitively for a few extra hours)?
Cause I dont care HOW BIG HP is: I dont care if its STAR WARS park or Lord of the Rings park, or even give it 2 years and attendance will level off again - and so will sales of merch. No matter what license it is, it always does.
(BTW: as to the robe/uber-fan thing, ever seen the entire 501st legion march at Disney in full Stormtrooper uniforms during Star Wars Weekends? Have to admit it puts the kids running around in robes at HP to shame!)
And no, not everyone wants to ride DC,heck Ive never even ridden DD/DC myself cause Im not a coaster guy!
But the argument that "its been around for 10 years" doesnt hold up either....first it has been re-themed, but aside from that: do you have ANY IDEA how many people I have met in the course of a regular day out at WDW that have NEVER been there and this is their FIRST TRIP? And its been around since 1971!
But again, not everyone vacationing in Orlando and going to IOA even this year is going because of harry potter - yes a lot are, but in this business you have to cater to the other guests too: the E-Ticket enthusiests, the roller coaster lovers, the casual day-guests, etc. And not all of them scheduled their vacations because of or even with knowledge of in a lot of cases about HP. The numbers of visitors to the area vs the number of people that hang out on these and other boards, blogs,etc is very miniscule...its just a fact.
