Are you talking June 2019? If so, I doubt that you can reserve that far in advance. I just checked Hilton, and the Hampton has tons of availability one month from now. I checked two weeks prior to and two weeks after your 2019 times, and got "no availability". I seriously doubt that it's booked that entire month.
That being said, I just stayed there for two weeks in June 2018 and had no trouble getting a reservation. Clean, reasonable, nice people, zero restaurants nearby, very limited and boring hotel food. Shuttle leaves every 40 minutes to airport. Hoofdorp train station is across the street, so you can hop on and go right to Schipol or downtown, which is what I did for dinner nearly every night.
I'm assuming that, coming off a cruise, you will have a ton of luggage. Unless you want to stay at the Hilton or Sheraton, which are attached to the airport (and are VERY pricey), the Hampton has no advantage over a hotel in the city unless your flight is at the crack of dawn. Not sure if you can get to Delft directly from the Hoofdorp station either. Hope this helps.
