La Isla Shopping Mall is hands down the coolest shopping experience in Cancun.  In fact, this mall is so much of an experience that even some of the hard core "I hate shopping" type of guys may just enjoy themselves.  La Isla is all outdoor and its huge. There are rivers running through the mall, there are statues that mysteriously come to life, there is an interactive aquarium, swim with the dolphins feature, a movie theater, and dozens of outstanding restaurants.  Oh, did I mention you can go shopping here too?  Located about 4 miles North of Yalmakan, about 10 minutes by cab, 15 by bus.
