It is hard to find things to do in V-town during the day if you are only a mild gambler/drinker, so props to Mandalay for trying to at least offer something different.  However, the aquarium was small and only took about 20 minutes to walk all the way through.  Slightly pricey for what it was, slightly \"sad\" if you've ever been to a decent aquarium anywhere else, and minus one star for the whole Excalibur-to-Mandalay Monorail nonsense that we went through trying to get there.
