I would not stay overnight at minute suites. No showers at ATL minute suites. You could use SkyClub on E or F if you have access but that seems like a hassle. Although for Super Bowl weekend, the Minute suites might make sense as all hotels have some crazy rates and none of the good ones are taking points reservations.
All three Marriott Gateway properties are on the first Sky Train stop. Marriott, Renaissance, and Spring Hill. All are new (under 5 years old). The Sky Train is the fastest hotel to airport link possible.
The Renaissance Concourse is the older property that is best for plane spotting. It sits directly along the runways near DL maintenance and the DL museum. You will need a shuttle bus to and from that one.
The Hilton is very nice as well.
