You really need to provide some additional information. Where are you staying? Will you have your own vehicle?
If you're staying on-site, then take the bus to the Magic Kingdom. You can either walk or take the monorail from there to the Contemporary.
If you're driving, you can park at the TTC and take the monorail to the Contemporary, or take the boat to the Magic Kingdom and walk from there.
As above, you can drive to the Contemporary and pay to Valet if you want to leave your car there the rest of the day.
You can drive and self-park at the Contemporary, but you'll need to move your car after you eat. There's a three-hour parking policy for ADR's, and the Contemporary is the main location where it's actually enforced.
