Target Field seating question
So I won a pair of tickets today, to next Wednesday's game. Only problem is, I would need 3 (for my wife and I, and our daughter). The two that I have have assigned rows and seats in section 108. I'm looking at the Twins ticketing site to look into purchasing one more seat, but it only gives me the option for the section, nothing about what row/seat it would be (so I'm assuming it would be assigned somewhere else in the section). Are they really that strict about which seats you have, or would we be able to just move to wherever 3 seats are available together?
