pete g is correct. The planet with the fastest rotation (meaning it spins around it's axis the fastest - not revolve around the sun) is Uranus with a rotation day of 7 hours and 14 minutes. Uranus lacks visible features but the Hubble telescope was able to track upper clouds to estimate this rotation time in 1994. Uranus also lies almost 90 degrees to the orbital plane causing it's north pole and south pole to point towards the sun during it's revolution instead of it's equator.
The incorrect answer is Mercury which has the second longest rotation at 59 days. Venus has the longest at 243 days.

I think the question was mis-worded. Planets orbit the sun, or revolve around it. If this is what you want to know, then Mercury is the winner.
The answer about Uranus being the fastest rotating planet would be correct if you're asking: "which planet around the sun rotates the most?"
No planet rotates around the sun - it's just a semantic of the English language. And yes, we're being picky. Nerds tend to be. ;)

Rotation is the spinning of a planet on its axis. Planets don't rotate around the sun, they revolve around the sun.
And I'm not sure what you mean by "have more".
So lets answer all the possibilities:
The planet with the fastest orbit (revolution) around the sun is Mercury - its the closest so it moves around the sun the fastest.
The planet with the most planetary days (rotations around its axis) in its year (revolution around the sun) would be Neptune - its days are only 16 Earth hours long but its year is 164.8 Earth years long (so it has 5639 of its days in one of its years).
Pluto has the longest "year" in terms of Earth years (even though Pluto is no longer a full planet but has been demoted to "dwarf planet" status).

The closer the planet is to the sun, the more times it rotates around it. Mercury has the shortest days because it's the closest.

The planet with the shortest year (shortest time to complete one orbit) is Mercury, the inner-most planet.
Measured in Earth days, Mercury's year is 88 days long.

Both Mercury and Venus have shorter years than the earth.
Mercury orbits the sun in 88 days.
Venus orbits the sun in 225 (224.7) days.

it's actually revolution
