Disappointed
We had picked the Grand Hyatt for the location and the name. After being here, it was obviously a mistake - the hotel does not cater to families (nor do they want to!) We had 3 children and 2 adults in our room and only 2 full size beds (this was confirmed upon registration.) When we asked for a roll-away bed, we were told that we could not have it due to fire code. So, we had to ask for blankets - twice within an hour!! Talk about a fire hazard!! We were left with only 3 bath towels in the bathroom each day so we continually had to call each day for more towels.
We paid extra to be on the Club Floor so that we would have breakfast, snacks and drinks. There was never any children friendly food. One of the staff did actually ask me one morning if my son would eat or drink anything and he said chocolate milk. She called to get it sent up for him. 
This was my 3rd trip to DC and 1st trip to the Grand Hyatt. I can assure you it will be my last trip to the Grand Hyatt!!
