Hi, long time lurker, first time poster. I want to purchase tickets for one of the St. Paul gigs and had a couple of questions. I've never been to a Coldplay concert, but I did see U2 last summer in the twin cities. I want to buy floor tickets but I noticed they had a row number and seat number. Does this mean anything? Isn't it first come first serve? My U2 tickets had the same thing but meant nothing. I would love some help figuring this out and any help is appreciated!
