Top Union Hotel Reviews

The Wildwood Hotel

10/10 Excellent

"The employees were nice, friendly and helpful. The room was roomy, clean and the bed was nice and comfortable. I really like that the B&B Theater was right across the street to walk to. We enjoyed a movie at the Theater."

Pinemark Inn & Suites

10/10 Excellent

"We had a very late (1:30 AM) check-in. We were greeted at the door. When the front desk was checking us in, we mentioned we hadn't had dinner due to delayed flights. She came out with a bag of bagels, yogurt, muffins and water. It was beyond appreciated! The hotel layout was unique. The room was great and very clean. Nothing but good things to say. We normally stay at top of the line hotels and were pleased at the level of quality and service."
