My sense is:
Having a separate name for the org and the hotel unnecessarily introduces more confusion/complexity.
Defaulting to Athena because it happens to be the name of the building already, seems highly improbable to coincidentally be the best option.
For clarity, something that concisely describes the mission or vision of the org and place feels best to me. Arepo's suggestion of 'Center for Altruists in Residence' hits the sweet spot on the specific enough to broad enough spectrum IMO. It also has an acronym which people will all pronounce the same and spell correctly (C.A.R.)
Using the names of philosophers etc runs the risk of people having (potentially negative) ideas about the person in question, which don't align with the purpose/vision/mission of the hotel. So personally I'd avoid that to ensure people who should be attracted, are attracted.
Great to see this here, Daniel! After a few years helping to run a local EA group and working for an EA org, my focus at the moment is how to bring EA and AR (Authentic Relating) together in the most impactful way. I've just landed a trial with a leading AR org with the hope that I can work with them to increase their impact. I also just ran my first online AR workshop with a bunch of EAs.
Your pitch for AR/circling to be a means of increasing the abilities of EAs to effectively spread our ideas is interesting! My initial thoughts are that the primary impact AR could have might lie in its capability to increase the quality of relationships in the workplace and thus the impact of the most impactful orgs. Secondly, as a practice to help people repair damaged relationships or to foster high quality relationships thus to increase individual wellbeing (this might be targeted at people doing particularly high impact work, or at people/cultures which could particularly benefit from these practices (prisons, schools...)
If you could persuade people of any professional background to dedicate their careers to working for the current core EA orgs, what kinds of backgrounds/skill sets/career histories would be represented which aren't currently?
If your worries about tractability are largely due to psychedelics being legally restricted, there might be reasons to be more optimistic:
Psilocybin mushrooms are now on the ballot to be decriminalized in Denver, there's a vote initiative in Oregon, and psilocybin is already legal in some form in at least 7 counties (including 2 in Europe): https://en.wikipedia.org/wiki/Legal_status_of_psilocybin_mushrooms
Ayahuasca is legal in at least 8 countries (including 5 in Europe): https://en.wikipedia.org/wiki/Legal_status_of_ayahuasca_by_country
