Tiki!
Polynesian Culture, South Sea Islands, Bali-Hai, Luau, Roast Pig and Pinapples, Sugar Cane, Hula Dancing, Tiki Masks, Tiki Torches, Tiki Drums, Ukelele-playing, Don Ho Hawaiian songs, Mai-Tais and other tropical Fruit-and-Rum drinks, Coconuts, Outrigger canoes, Wildly colorful shirts, Grass Skirts and Lava-lavas, Leis made from colorful tropical orchids (Imagine getting lei'd), feasts and sacrifices to Pele the Fire Goddess, Menihunis (sort of Hawaiian Leprechauns),...
...All sorts of things to work with there, from every south seas island movie or Joseph Conrad novella to Cargo Cults, Windjammers sailing between exotic locales from Tahiti to Rabaul, dark and mysterious islander customs and taboos to play into story plot lines, something to build a Pawpet Show around, and all sorts of lobby props, what's not to like?

...If that isn't suitable for consideration, then I'll again suggest Furries on the Orient Express, and that whole pre-WWI era of Grand Travel across The Continent, when the world was so different from that of today.
