I would say, in many cases, we could consider veganism to be a major inconvenience.
when the whole family is eating meat and one has to live with them.
when one cannot really choose in school or work because of cafeteria offer
when one doesn’t have a belief animal suffering should be avoided
when one has low tendency to stand up against colleagues/friends/family/society pressure
when one doesn’t know how to cook (or doesn’t have time) and there are not good enough vegan services in place of living
But when you change the context to Hotel for effective altruists where one can just eat what is given, is supported to eat what’s given by everyone around we could call it only a “minor inconvenience”. And in a case, the food will be really good it could be called “great opportunity” for non-vegan EA to experience vegan living without even trying.
