Yeah, I agree. The other problem you could see would be the park closing to capacity even though the other rides might be seeing minimal wait simply due to all the people standing in line for SW:GE. If you have (my numbers are purely for illustration, I have no idea of actual park capacity) a capacity of 40,000 people total and 25,000 of them are there for SW:GE, the remaining 15,000 will have very low waits on the other rides but the park will still be "full" of ONE.BIG.SCARY.LINE.
Am I way off base (other than my numbers, as I said)?
