The realignment to which you refer is the dropping of the Hyatt affiliation for the hotel formerly called the Park Hyatt. It is now, as I recall, a Meridien. I had stayed there, when it was a Hyatt, many times, with great satisfaction. The Grand Hyatt is an adequate hotel, as is the Hyatt Regency. My wife prefers the former because it is in the center of Union Square shopping, and I prefer the latter because of the shape of the rooms (angular so that there are more or less good views of the Bay) and its location. The Regency is located on the Embarcadero. Another choice, one which we seldom choose, is the Hyatt at Fisherman's Wharf. The hotel is OK, but the location is not optimum for us as very frequent visitors to SF. If you choose the Grand Hyatt, I think an upgrade to the Regency Club would be desirable, if allowed and the payment is reasonable ($30 or $40), since the views from it are spectacular and the offerings are fairly good, including a nice array of breakfast items.
