I would look into taking a cab to the Beacon Metro North station. Beacon is 2 stops from Poughkeepsie
Rental car would be a good option , no public transport
According to the hotel website no shuttle is provided but here are the options: Alternate transportation: Mid-Hudson Limo; fee: 60 USD (one way) ;reservation required Estimated taxi fare: 55 USD (one way). Or you could rent a car as well. Enjoy!
Uber
