As of 2017, Denver International Airport has been rated by Skytrax as the 28th best airport in the world, falling to second place in the United States behind only Cincinnati/Northern Kentucky International Airport. Skytrax also named DIA as the second best regional airport in North America for 2017, and the fourth best regional airport in the world.
Denver International Airport (IATA: DEN, ICAO: KDEN), commonly known as DIA, serves as the primary airport for a large region surrounding Denver. DIA is 18.6 miles (30 km) east-northeast of the Colorado State Capitol. DIA is the eighteenth busiest airport in the world and ranks sixth in the United States, with 58,266,515 passengers passing through it in 2016. It covers more than 53 square miles (137.3 km2), making it the largest airport by land area in the United States and larger than the island of Manhattan. Denver serves as a major hub for United Airlines, is the headquarters for Frontier Airlines, and is the fastest-growing focus city for Southwest Airlines.
Will you actually be staying overnight at a strip hotel? If so, easiest to leave your bags at that hotel. Or will you be flying into the airport on essentially a layover for 8 hours? It'd be easier to just leave your bags at the airport if so, and in that case, I don't know if there's storage areas there. I'm thinking not, so as suggested above, just take your bags to the bell desk at the hotel/area you're going to be visiting. The bell desk will be located right by the front desk check-in area, right by the front doors. Obviously, choose a hotel where you'll be hanging out by.
