90 LY at warp 8 is only 32 days travel time each way.

But normal cruising speed is only warp 6.
It's possible to travel faster than that, of course,
but only for limited periods since it accelerates deterioration of the dilithium crystals.

Not from TNG on.

Look how fast Defiant can go for the length of time it takes.

And I swear, I'm not uncoordinated, don't wear orthopedic shoes, and didn't have to take my mother to the prom....
