I am flying AS from DCA-SEA and back later this week. As CRC/Sky Club member, I know that I can access the AS Board Room lounges at SEA. May I also bring a guest?

Thanks in advance. I couldn't find an answer either through a search or on DL.com. The latter contains an ambiguous statement that only CRC/Sky Room members may access the Board Room, which I presume means that DL first class passengers/DL Reserve cardholders/etc. cannot access the Board Room and does not address the guest/no guest issue. For what it's worth, AS's website says that Board Room members may bring 2 guests into CRCs, so I would hope that the same rules apply in reverse.
