We have stayed at Mohegan Sun and The Bethlehem Sands and loved both places. We were so disappointed in MGM that it made us anxious to leave. Check in was a cattle shoot that took over 40 minutes before we got to the desk. The room was tiny with an open bathroom (no real privacy at all). We had to hike almost a half mile for coffee as there was no pot in the room.
We hated and I doubt we will ever go back.
