Annual passes are a great way to enjoy a number of Tampa attractions all throughout the year and save some cash while doing so.  For those who frequent Lowry Park Zoo, MOSI, or the Florida Aquarium in Tampa, with these passes, the deal just got a little sweeter.

It's called Swaptember.  From September 4 through 30, annual pass holders at any one of these three fun-learning Tampa destinations get free admissions to the other two for free.  Annual pass holder at the Florida Aquarium?  You'll get unlimited free admission to Lowry Park Zoo and MOSI throughout September.  Lowry Park Zoo? Free, unlimited admission to the Florida Aquarium and MOSI.  You get the idea.

Each of these family-friendly attractions offer unique, entertaining learning experiences for adults and kids of all ages.
