Quoted from bluespin:I stayed at the Wingate last year. The room was very clean. The bedroom was updated but the bathroom was dated (cracked tiles), but again it was very clean. They serve a free continental breakfast and I think the rate was ~$79.
I'm local and I can tell you that the Wingate is the newest of all the hotels mentioned above. Also, there are several hotels on Airport Road, Microtel, Homewood suites, and Marriot chain (residence inn, courtyard, fairfield). Another really nice hotel is the Hotel Bethlehem. A bit farther but nicely situated in downtown Bethlehem.
