I am headed to SF end of May and wanted to do the night Alcatraz tour for either Saturday or Sunday night. Of course I just checked and both days are sold out for the night tours. Does anyone have any advice on how to obtain tickets for the night tours if they are sold out? Willing to pay a little more than they are worth at this point. My gf told me to purchase them a few weeks ago and of course I didn't and now they are gone. Hopefully I don't have to break the news to her as she was excited to see it at night. Are we S.O.L?
