Also look at airbnb. Cost will usually be a little higher than a hotel, but you usually get more room and a full kitchen which can save you some money.
Most left are on the east side of the river, so you will either need to take the bridge or the Garrison/West Point Ferry. Won't work for R-Day. May work for other visits.
If you do Facebook, search for West Point Harborcraft.
