There's definitely precedent - small math conferences are often held in interesting locations, and everyone gets a travel grant to attend. Just need a couple meeting rooms for the sessions during the day. The more niche the field the smaller the conference - not talking about big resorts here. Machine Learning Summer School (MLSS) used to have some nice locations, don't know what it's like these days. You could go with a name brand, Brian Greene type. Like a "MasterClass Live" type thing.
