Average section but not all that far from the action down on the field, this came to realization when we got to our seats. Had no trouble making out who each player was and where the ball was. The running plays are boring when you sit so high because the speed looks so slow. If at all possible, buy your seats in the first three rows of 446. Those rows are secluded and there will be no fans walking in front of you.
Tickets for most upper level seats will generally be priced in the $60-$90 range per seat. Not cheap but also not a ripoff. Dolphins games are a pretty affordable outing by NFL standards. We paid $100 for two seats.
Getting to the upper level seats could become confusing for the fans that have never been to a Dolphins game before. There are escalators inside each corner entrance of the stadium. Gate H is the gate you will went to enter if you're tickets are in section 446. You will also have the opportunity to take the walking ramps to the top which will take a little longer. Those are in all four corners of the stadium too. Once you reach the top, section 446 will be right on your left. An usher will more than likely stop you to check your ticket but not always.
Really wish there was more of a neighborhood surrounding the stadium but I guess it's not all that different from Fedex Field in DC or Raymond James stadium in Tampa.
