We’ve seen our fair share of unique hotel design elements, but the sheer number and grandiosity of on-property hotel aquariums took us by surprise. While some are in locations where you might expect to find elaborate shrines to the local ocean flora and fauna – Hawaii, the Bahamas, the Philippines – mega-aquariums have turned up in some unexpected places, like central Berlin and midtown Manhattan. A pair of Vegas showstoppers, a duo of Florida hideaways, and a monstrous aquatic playground only possible in everything-to-the-extreme Dubai round out our list of the largest and most extravagant. And unlike the tanks you may have encountered during grade school field trips, these 10 hotel aquariums aren’t just for pressing your nose against the glass: Some allow guests to plunge right in through scuba or snorkeling sessions, stingray feedings, or dolphin encounters. So take it from us – it really is better down where it’s wetter, under the (artificial) sea! Check out our Hotel Aquariums slideshow to get a sneak peek of these watery wonders.
