I know it is early, but decided to start trying to book two rooms for a 4* or 3.5 * room in downtown SF. So far , no luck. I tried Union Square East at $101.00 and got not results, came back and added 3.5 stars and added zone 12 at $106.00 . no luck and then tried zone 2, 3 and 1 , each time adding a little money all th way up to $116.00 , but nothing. Will try back tomorrow. Any tips . I will say, usually, it takes several seconds for the results, but each time, it was an instant no. Not sure if that is a bad sign. For a 3.5, it said the average cost for $209.00
