I was at the Days Hotel for a a park and fly for a trip to Florida. We found our room very clean. We found the staff very nice. Michael at the Front Desk was helpful and went above and beyond for us. The park for the park and fly was right next to the building and we were able to get a spot close to the hotel. The breakast was perfect for a light meal before a flight, and they start it really early. We didn't have a long wait for the shuttle to the airport either. Upon returning, the shuttle driver was really nice when we returned from Orlando, he drove us right to our car and helped to clean the snow off.
Although we didn't make use of them, there was a pool and a exercise room too

On several recent trips, the most recent January 2012, we have stayed at the Days Hotel Buffalo Airport when flying out of Buffalo. The park 'n fly offered by the hotel is a great option. This is a good basic hotel with a continental breakfast (good coffee) to get you started in the morning before the flight. The location is very convenient with an on-demand shuttle service to and from the hotel. Front desk staff is very friendly. I wouldn't hesitate to recommend this hotel to those looking for a park 'n fly hotel stay at Buffalo Airport.

I recently stayed and the Days Hotel Buffalo Airport, using their Park & Fly option. The hotel is located right across the street from the airport and is super convenient. I stayed there one night (hotel is a bit dated but was clean and just fine). The breakfast was simple and the room was good. The Park & Fly is a minute away and there is a shuttle to/from the airport. All in all, a solid value.

Clean and basic hotel near the airport. Decent continental breakfast. Would stay again.
