In order to get the Thrill Seekers you have to get it stamped at AK first. Also, when we were there on Sunday, the person at the register told us they were out of one of the cards from the Thrill Seekers quest that you get from MK. As far as getting the quests, we took all of them to VMK, the printed ones and the quests that come in the brochures and the person at the register looked them over to make sure they were correct. We then gave her our passes so she could enter in the register that we had completed the quests on the tickets we provided. She then gave us all the cards. It was really simple. I'm not sure it will be crowded when you go, but on Sunday, there were two separate lines at VMK Central, one for purchases and one for VMK. Make sure you get in the correct line. There were some people who didn't and they weren't too happy with the extra wait.
