Well, here is a paste from the post about halfway down this page from someone who actually did take a water-damaged Mac into the Genius Bar:
"Happy" story. My daughter got a liquid spill on her MBP. She brought it to an Apple Store where they told her the liquid spill was not covered by her Applecare. She brought it back home, we sent it to Apple Repair (called the support line and they sent a box); they informed us it would cost about $774 (plus tax) to replace logic board, and 'make the computer better than new." The rep recommended I call Homeowner's Insurance (Amica), and since we had a computer/electronics clause for a nominal year charge, indeed the computer was covered for repairs or replacement, whichever was less (we were covered up to $4K) with a $50 deductible. The computer IS better than new now. Buy that extra insurance - either homeowner's or renter's. The ins rep told me our smartphones, iPads, iPods, laptops and desktops, etc. were all covered. "Even if you dropped your phone in the toilet."
So, it sounds like you would do better to contact the Support line and talk to the Apple Repair people. Here is a link to do that.

According to this support page, you should be able to bring in your Pro to the Apple Store to have it analyzed. It does not appear that the poster of this story was very successful in the Apple Store visit, but that may vary from store to store. I don't know. But, if you don't want to give that a try, then you can call the support number for your country below, and talk directly to Apple to arrange to send it in to them:
