Shark Reef at Mandalay Bay Resort
Pretty good aquarium, long lines to buy tickets, to get in, but they moved fast, one plus is after touring facility we found out they actually clean the audio wands after you use them, aquarium had a pretty good amount of specimens, Large size (1.6 million gallon) but not massive like some others around the country. Price was I believe $17 to get in, no discounts with AAA, AARP, or senior
