We booked a 12 day Baltic Cruise on the M/V Celebrity Constellation, with 2 pre & 1 post cruise stays at the Crowne Plaza and Hilton Airport Hotels respectively in Amsterdam. Both hotels have complimentary airport shuttles, but one can easily walk to the Hilton either from the outside or via connective inside walkway from the second floor of the Amsterdam Airport, unless you have lots of luggage.
The Crowne Plaza is a relatively new hotel, while the Hilton is classically dated, with a new one being built across the lot. Both hotels were very clean, quiet and comfortable, with the Crowne Plaza being more spacious. As we were at the Hilton on a weekend, we do not know how bad the construction noise, if any, would have been.
WiFi is expensive at the Crowne Plaza, but complimentary, if you are an IHG Rewards Club member. WiFi is complimentary for guests in the lounge area of the Hilton.
