This was a business conference that originally was booked for February, which I attend annually. Due to fires in Pasadena, it was moved to July. I was not given a refund, but only a credit and had to pay a large difference when rebooked in July. I have stayed at the Hyatt before and it is a nice accomodation, but their new air conditioning/air flow system is awful. It is only motion sensored only, so when you are sleeping, the fan turns off. It got extremely uncomfortable and warm and stuffy at nighttime. I called for maintenance to come and just turn on the fan, they cannot override the ecosystem that is motion sensored only. I asked for a desk fan or anything and they could not accomodate. I then ordered small fans from amazon. I will not stay here again. I paid entirely too much money to not sleep well.
