I've never bought a dedicated housing for a non-action camera for precisely that reason— they're so damn expensive! And then any I've been tempted to purchase and have fit the budget have always had sort of dicey reviews on Amazon. 😅

I definitely recommend grabbing a GoPro next time you're in the market for a travel/vacation friendly camera — it's so convenient for trips like these where you can't/don't want to lug around an actual camera (whether it's a waterproof point and shoot or inside a housing).
