You're right about the idea, but a few hours is way too short, because of how the Human body tolerance to strong accelerations.

Assuming an acceleration of 10 m/s^2 (similar to Earth's gravity), it will takes roughly one year to accelerate to a speed close to the speed of light were relativistic effects occurs, and you will need one more year to decelerate.

Once again, it will be easier to bring people to the data, than data to people.
