Oh--okay--
We must have had Cat 1 tickets when we booked (though that was almost 5 years ago, and hubby didn't mention anything about less expensive seats). We were 2nd row and it was actually pretty cool.
I agree, any section is probably okay--but I like detail and seeing things up close. Though it was difficult in Cat 1 to see the beginning of the show (not sure if people know how it begins and don't want to be responsible for spoiling it).
The only discounts I have seen are buy one get one half or free deals and those have been for either FLa residents or just show up and get them (I don't recall where I have seen them, so please forgive me--I'm not even sure if it was available only for a certain category).
Do best what your budget can afford--if you are the type of person who likes to sit on the 50 yard line first section at a football game, front row at any stage show or concert, or front row tix to a b'ball game--then you probably will not be disappointed with choosing the 1st section.
I haven't sat in the 2nd section so cannot compare the two adequately to say one is better than the other.
In the past--the sooner you book, the better your seats.
