Sometimes these hotels give the worst experience, sometimes they charge so high and the service is just stupid, you just think before visiting any other hotel again, these kinds of issues are really common for me even when going somewhere local. I think sometimes it's often better to visit your family and friends who are at that place, it's way more easy and comfortable to stay with them and have a good time enjoying your trip...
Besides these hotel issue, I do think you might have enjoyed the concert and had a good time!
