Disappointing experience for the expense
I was one of a party of eight staying at the Grand Hyatt to celebrate a 60th Birthday, we had three rooms between us for the duration of the stay. We were there for five nights from 26th - 30th October and sadly hurricane Sandy gate crashed 2 days in to our trip meaning we were pretty much confined to the hotel from Sunday night to the Wednesday (when we checked out) as 99% of shops and restaurants were closed for the storm which hit New York City on Monday 29th. 
When we checked in on the Friday we were made aware that there was a storm heading towards the city in a few days, so the hotel were well aware and as we thought had taken all steps necessary to make sure it didn't compromise our stay.
Each of our three rooms were issued letters on the Sunday explaining that there would be limited services during the storm, including room service and house keeping. Despite having staff deliberately staying in the hotel, so as not to jeopardise their safety traveling to and from work or potentially have no staff be able to get to work because the public transport going out of service during the storm, there was still a poor service in place.
All three rooms were not made up for the last two days. One day we asked for new towels which took 8 hours to come to the room. The hotel made no effort to make up for this, no negotiation was made with any other services, in fact the food prices were put up for the three affected days. It cost $1000 dollars per day for the eight of us to eat a buffet of breakfast ($29 per person), lunch ($39 per person) and dinner ($49 per person).
Movies in the room were still full price, wifi was still an extortionate $17 per day. The wifi even went down during the storm and I had to go and ask for the money back, this should have been done automatically in my eyes.
Upon checkout and paying full whack for everything, the hotel had the audacity to charge us $2 per piece of luggage to be held securely for 4 hours until our taxi came to take us to the airport. When there are 8 of you and 11 suitcases you would think they would throw you a bone but... no.
It was a nice hotel but a huge shame that they didn't handle the situation any better, they took advantage of the situation and made money out of it. We will all think twice about staying there again.
