A problem for business travellers
I stayed at the Grand Hyatt in early October 2012. I was on a business trip and highly dependent on my computer to operate in the hotel. When I tried to get connected it would not work; I was connected by the hotel operator to a service in Guatamala City - and was on the phone with a young man for 2 1/2 hours while he tried different things to make it work - explaining in the course of it that the servers in the hotel had a weak signal in some rooms and maybe I should change my room. I finally gave up and went to bed; the next morning I was able to connect by disabling virus protection - a very unsatisfactory resolution that he never even suggested.
Aside from that the room was clean and pleasant - but without good computer service, it is a real problem for a business traveler. I rate the service and facilities as excellent except for this problem - but this problem was really important to me and it left a bad taste in my mouth.
