They really don’t do that (serve as a travel agent), and AFAIK never did. What they used to do was offer “consultant” services (required pre booking a consultant, and charged by the hour). - but they never actually booked things (except their tours, of course). I believe the “consultants” went away with COVID, and never came back.
As I recall, what they used to do when asked for “travel agent” services was to refer customers to a local travel agent who had an actual brick ‘n mortar shop just down the street (Elizabeth Holmes - which seems to have moved about 10 years ago, and is no longer in Edmonds). Don’t know who/if they recommend anyone these days.
Worth noting: These days the RSE HQ in Edmonds is only open on Saturdays (another post-COVID artifact).
Honestly, “travel agents” are a bit of an anachronism, made largely obsolete by the internet and restructuring of commissions (how they used to make money). There are still some around (though some of those who survived may not be very knowledgeable - we see people tell hair-raising stories here of “travel agents” who seem pretty clueless, so caveat emptor). There’s a small number of travel agents that specialize in very high end clients, but it’s a tough business model. Frankly, for most people, the best travel agent they’re going to find is going to be the person they see when they look in a mirror.
Hope some of that is helpful. Good luck.
