Drumm Street in front of the Hyatt Embarcadero is under construction and it looks very messy
The hotel is still open but expect minor traffic delays if driving in and out of the hotel. Although the BART/MUNI entrance right in front of the hotel is closed, visitors can use the other entrance (A2) a block away. Those waiting for the cable car at the turnaround will have to wait next to construction equipment or walk a short block down California to the next cable car stop. The taxi stand has moved to the corner of Drumm and California.
The construction is expected to last until Spring 2014. But all in all, this looks like it should only be a minor inconvenience as the hotel and all transit stations are open and not under construction.
