We were seated almost directly behind the uprights in the East endzone but 427 sits high enough that it really wasn't a problem. The rows are pretty wide in the number of seats. I had seat 24 in row 11 and that was an aisle seat. So the closer your seat is to seat 1 or seat 24, the closer you'll be to the aisle. Keep in mind that you'll have to stand to let other fans out and this can become bothersome throughout the game but it could vary. There was plenty of space to put the items we bought from the Dolphins team store which is in the Grand Plaza.
The Dolphins are planning a series of renovations for Sun Life in the future and it needs it. A stadium in downtown Miami should be considered when they build a new one, this place is so hard to get to depending on where you're coming from in Miami though not quiet as bad as where the Panthers play in Sunrise. Concessions lack variety and unfortunately, you'll be coerced into buying concession food because there are no restaurants near the Stadium.
