As mentioned Old Pasadena is right up the hill, lots of bars. If you take the shuttle down to the game and then back up from the Parsons lot you will be in Old Pas.
Im staying at the Courtyard Marriott in Old Pas, the last game I went to the RB two seasons ago it was quicker for us to walk back to the hotel after the game than wait for the busses to go to Parsons, the line was long but there were a lot more people at that game then will be at this one.
