I had a FFN stay on Nov 26. The hotel was fine until about 2am when the ceiling was creaking so loudly that it woke us up. I called downstairs to see if this was normal and they said that since it was very windy outside and the building had been retrofitted for earthquakes, there was nothing they could do. They offered to bring up earplugs! They also said that every room in the hotel has this problem when it's windy and they had received several complaints that night.

We were scheduled to stay for 2 days but we checked out the next morning. The manager was very helpful with transfering our FFN room to the Park Hyatt which was very nice and very quiet. He wasn't really keen on doing this since he admitted that their hotel gets revenue from Hyatt for FFN stays but he finally gave in.

Maybe we were just unlucky that it was so windy, as this is probably pretty rare in SF but after this experience, we will not be staying at the Grand Hyatt again when in San Francisco.
