I would have no fixed amount of rooms for paying or non-paying guests.
I think having at least some rooms reserved for each is actually pretty important. If there aren't any non-paying guests working on projects then you lose out on the networking/synergy/culture of productivity, which is the main reason the hotel is interesting in the first place. Not having rooms for short-term paying guests also seems like a failure mode, for cultural reasons: the hotel's status as a "destination" raises its own visibility and attracts more projects in the future, but I think even more importantly it serves as a symbol of the community. Taking a train out to the countryside to stay in a hotel where a bunch of EAs are incubating their projects is the sort of emotionally resonant experience that strengthens people's bond with the movement, and is also the sort of thing that is interesting to talk about and will organically raise the visibility of effective altruism as a whole.
You need a critical mass of people working on projects to develop culture, and enough short-term visitors to disseminate that cultural product. Too much skew in either direction makes the whole thing less impactful.
