We booked a room to stay for one night while attending a concert at Mohegan sun. The staff was not friendly at all and the woman who checked us in seemed to be doing us a favor. The shuttle didn't start until 6pm so we opted for a cab in order to make our 5:30 dinner reservation. During check in I asked to sign up for the last shuttle leaving at 12:20am. In a dismissive fashion, the lady said "you're all set" and we were on our way. Fine.
12am rolls around and we get out to be ready for the shuttle. At around 12:25 I call the hotel to ask if it is on the way. I was informed by a lady that it had already left and that we were at the wrong entrance. SHE LAUGHED AS SHE TOLD ME THIS. Because of the stellar check-in experience, we had no idea to be at any specific entrance. We had to pay for ANOTHER cab ride - $40 in cab fairs for the night.
I will never ever go back to this Marriott and will only refer people that I don't like. I'd suggest staying somewhere else when visiting the casinos.
