Is Wulinmen CAAC Ticket Office very near Courtyard/JWMarriott?

We're 60 yrs old couple arriving HGH airport nearly midnight. If we take shuttle bus to CAAC, do we have to walk very far to our hotel at Courtyard? Is it safe? Should you recommend a taxi, how much will it cost and do we need to pay extra for our luggages? Thanks so much for the reply.
