I see you are from Massachusetts so expect you will be arriving by car.
Each time we have arrived, there has been a stevedore immediately at our car to take our luggage. Very pleasant and efficient. (They are appreciative of a tip, of course. :: )
You will be directed to which doorway to enter and will see HAL's shore ops people in their red jackets/vests available to direct you, answer any questions etc. Take the escalator/elevator to the upper level and you will find a long counter with many people working on check ins. There are always at least 15 work stations.
Then it is an easy 'aboard'. `
