This might have already been answered, but I can't find it, so I'm just going to ask. The Silver pass has 4 randomly assigned captain's talks, and I assume we'll find out in advance which ones, like for the autographs. But how far in advance are likely to find out which talks we get, because I really want to see Kate Mulgrew, but I don't want to find that's the one I didn't get then have the tickets for it sold out because of when I fould out. If that makes any sense.
