I did a tandem jump in 2014 at Perris, with no real idea what I was getting into. When I landed, all I wanted to do was be back in the sky. I spent the next couple of months saving money and gathering information and eventually made my way to DeLand in December, to go through the entire AFF course. Much like you, I wasn't worried about freefall, but the canopy flight and landing was daunting (until it actually happened). So much so, that I was shaking as I boarded the PAC. The freefall was great, the opening, smooth. Canopy flight was uneventful. Just make sure you're aware of the winds and your landing pattern prior to the jump, then check the windsock before you turn for your downwind. Your instructor will be on the radio with you, but never rely on technology. Don't be afraid to ask questions and always listen to your instructor. Blue skies!
