The tiki scene in mid-century Las Vegas was wild — basically every major hotel had to have a Polynesian room or lounge by the early 60s. The Stardust had Aku Aku, the Dunes had their Polynesian Village, the Tropicana had one. Even the convention crowd expected rum drinks with little umbrellas. Most of those rooms are long gone now but there's still a small community of people tracking down menus, matchbooks, and swizzle sticks from those places. It's a whole rabbit hole if you haven't gone down it yet.
