Spice up your next vacation with a little adventure. Choose something family friendly like hiking, biking, swimming with the dolphins, horse back riding on 
aCaribbean beach, or a day hike in Hawaii, St. Lucia, or Alaska.
For even more adventure, consider whizzing over treetops along zip lines on a canopy tour, scuba diving with sharks in Australia, an ATV Safari, River Tubing, and more. And for the thrill of a lifetime, consider a parabolic (zero gravity) flight.
Parabolic (Zero Gravity Flights)
When gravity is switched off, nothing behaves the way you would normally expect. There is no up or down, and objects are no longer heavy or light.
Board a specially equipped, FAA certified Boeing 727 aircraft that simulates weightlessness. The aircraft's interior has been converted into a zero-gravity playroom complete with padded flooring and video cameras to record all the fun. The NASA-approved aircraft is similar to that which is routinely used to train astronauts and cosmonauts for their space missions.
