Your response provided no practical help whatsoever and wasn't worth posting. If the problem hadn't resolved istself, of course a repair by Apple was the obvious next step.
However, for others who spill water on their keyboad or trackpad, my advice is to gently wick away as much liquid as possible with paper towels, kleenex or other absorbent material until the surface appears completely dry. Power down the computer as soon as the spilled liquid is under control. Then, invert the computer 180 degrees to drain any liquid which has seeped inside the keyboard and trackpad. You may well find you need to soak up new water droplets with a kleenex or paper towel following inversion as I did. Be careful not to angle the keyboard while inverting since you want to prevent water from draining into other parts of the computer. Don't shake the computer as this may cause the liquid to move around inside the unit. Place the powered down keyboard/trackpad facedown over a cool fan to dry for several hours. The best approach for this I found was to use a ventilated crate with a fan inside it blowing air straight up into the keyboard/trackpad from below. This allows excess water to drain down out of the computer while circulating air through the spaces surrounding the keys and trackpad. One person recommended placing a towel between the fan and the keyboard to wick water out of the machine, but this also reduces airflow to the keyboard, so blowing directly onto the keyboard seems to me equally good. I would advise against using a hairdryer or hot air blower since electronics can be damaged by heat. In my case, I propped my open MBP against the face of a cool fan for 5 hours before powering up and finding the problem had completely resolved itself by drying out. Immediately after the water spill onto the keyboard and trackpad, my MBP initially worked after toweling it off, but the trackpad unexpectedly became ultrasensitive to small touches and then went dead after about twenty minutes of use. It was completely unresponsive and would not depress or click with even a very firm touch. I could still move the cursor around with the arrow keys, but the trackpad was completely out of commission. I basically followed the procedure I outlined above and my trackpad functionality returned once the computer had completely dried out. I have had this problem on three occasions with earlier versions of MacBook computers and have thankfully seen full recovery each time after the keyboards and trackpads dried out.
