You'll have wonderful visibility through a canopy instead of a tiny airliner
window.
You may be surprised at how quickly and steeply the glider banks and turns,
compared to an airliner - but that's half the fun!
It may be turbulent (bumpy), as others have said, but you'll be strapped in
with a harness, not just a seat belt. Often the tow feels bumpier than the
glide, because it's a bit faster.
Sunglasses and are highly recommended.
Have a great time!

I'll be taking my first glider ride this week (not soaring, just
gliding) and was wanting a description of what to expect. I've never
flown in anything but a passenger jet, so that's my only frame of
reference. We'll be using an ASK 21 model. I've been told gliding is
like floating down with no sound, but that sounds too easy. What is
the turbulence like? Is it shaky at all? Cold up there? How safe are
the newer gliders? Thanks for any info on what to expect, it is
appreciated.
