You will have limited options given the time of your arrival. The last Alilaguna boat (Orange Line) leaves the airport at 12:15 am, so it is doubtful that you will make that. You can take a taxi or the bus from the airport to Piazzale Roma, this is the end of the line for land vehicles. From here you would normally take the Vaporetto, but the Night Line does not stop at your stop, which would be the Tre Archi Terminal. Your hotel is actually close enough that you could probably walk from Piazzale Roma. I would estimate that it’s probably about a 12-minute walk.
Another option would be to take a private water taxi, which will be very expensive, but they will take you right to the doorstep of your hotel. As you can see, there really is no best option after midnight if your accommodations are not located close to a Vaporetto stop on the Night run.
