Families love this full-day tour. It begins with a once-in-a-lifetime experience that sees you swimming with dolphins at Cancun's dolphinarium. You'll take to the water in groups of around 15 to interact with the animals for about 40 minutes. During this time, you'll experience a fin shake and a kiss, and get the chance to stroke their rubbery bodies. They'll show off for you, too, speeding through the water and jumping into the air to perform 360-degree flips. Later, you'll be let loose in the neighbouring Wet ‘n' Wild waterpark. There's everything from lazy rivers to adrenaline-pumping slides here. A couple not to be missed are Bubba Tub and the Double Space Bowl.
