My daughter and I and her 8 month old have a long layover at OAK in January. (arrive 1:13 pm, leave 6 pm). Seems like a long time to spend in the airport - is there something we can do in that time and still get back to the airport for our flight? I am thinking of taking the BART to Fisherman's Wharf or something like that. Is there anything safe and fun in Oakland? Other suggestions? Thanks!
