The above answers are more or less correct.
You can experience zero gravity in three ways:
1. accelerate to and maintain the escape velocity of the earth which is 40,000 km/h, or alternatively achieve sufficient speed to orbit the earth in outer space where your centrifugal force equals the force of gravity (you have already disqualified this option).
2. accelerate toward the earth at G which is 9.8 m/sec^2, for example in the "vomit comet" which I believe is a 707 or 727 not a 747.
3. travel to the center of the earth where the gravitational field of the earth would be neutralized.
So unless you are an astronaut, the only practical solution to experience zero gravity (0G) is to be in a plane that is accelerating toward the earth at 9.8 m/sec. That is usually achieved by a nose-down maneuver after a climb, so that the airplane and all its contents are weightless until the VNE is approached, which the pilot then has to correct for by levelling off. Most small aerobatic planes such as the Citabria can do that; ask at your local flying club. On a commercial flight in turbulence you can experience 0G for a split second sometimes, but its not long enough to get a real sensation of what its like.
Being suspended in a column of high-velocity air in a silo allows you to float, but does not allow you to experience zero gravity. Same goes for free-falling through the atmosphere (except in a plane or other falling object) as the drag of the atmosphere equals the force of gravity at terminal velocity, which results in exactly 1 G of force on you.

Three places:
a) In a diving jet airliner, which is in free fall, and so the occupants experience true zero gravity for a few seconds. They take passengers, but it is very expensive (thousands of dollars)
b) In a disused silo or grain elevator, fitted with a propellor at the bottom, and a metal mesh to separate the occupants from the propellor blade (of course!). The air flow from the propellor is adjusted so that it cancells out gravity, and the occupants float (but experience a very strong up-draught). I don't know if there is one of these facilities in the USA, but there used to be one in NSW, Australia.
c) Parachuting. You'll experience zero gravity when you are in free fall, but there is a lot of wind shear. There are plenty of tandem sky diving places, and it's not too expensive; if you are game.
d) Cheap alternative: jump off a diving tower at a swimmig centre, as high as you dare. You'll experience zero gravity, until you hit the water..

a zero gravity simulation can be done in a deep tank of water. technically you wear a suit that has neutral boyancy at a certain depth. of course the effect is limited to a few feet vertically before you start feeling those tell tale tugs of gravity or floatation. but within the zone you can turn and drift as if there were no gravity. there is still water resistance to movement, so in that way it is not like outer space.

Absolutely! And this is something I've been wanting to do but it costs $$. In Florida (and other places) you can pay to board a specially modified 747 that flies in a parabolic trajectory (up and down like a rollercoaster). When it flies down you and the plane are falling at the same speed so it feels like zero G for maybe 20-30 seconds. It repeats this several times. Search google for websites that offer this service.
