Very disappointing
We booked for four nights for the end of October 12 but Hurricane Sandy meant that getting into NY was impossible for the first two days. We had previously emailed the hotel that we would be late but wanted to keep the remainder of our reservation, and received emailed confirmation that we would not be charged a cancellation fee. On arrival, we again confirmed that no cancellation fee would be charged. Despite our reservation having been cancelled (against our express email request), the front desk staff were very helpful. Our reservation was reinstated, we stayed at the hotel for the two days and the location was really good, given the difficulties for Lower Manhattan. 
Prior to departing, we received an invoice for two nights that reflected our agreed rate. However, we later found an additional credit card charge which was a cancellation fee - without invoice or other advice from the hotel. It has been one month since we left NY and we are still having difficulty getting a response from the hotel and have received no advice on the refund of the cancellation fee. This is unacceptable service.
