capecad and I did this tour last month
When you go to the Magic Kingdom, go into VMK Central which is on the right side of Main Street USA. Ask for the Quests. They will hand you 3 (I think!) folders that look like big scratch-off tickets. There are several questions on each Quest folder. You have to scratch off the gold spot next to the correct answer. You find the answers by walking around the Magic Kingdom, hence the name "quests". You are on a quest to find the right answers
Once you have them all completed, you bring them back to VMK Central where a CM will check them for you. Once you have all the right answers, they will give you what looks like a trading card. You take this trading card back towards the entrance of the MK, to Town Hall. Inside Town Hall, there are CMs who will then schedule you to go on the real VMK tour. The tours are twice each day and last about 2 hours. They only take a limited number of people on each tour. The tour times are about 1pm and 4pm, or something like that (maybe 1:30 and 4:30?).
Anyway, on the day that your tour is scheduled for, just show up back at VMK Central and the Tour Guide will give you a badge with your name on it.

Then he takes you around the Magic Kingdom. During this time he will ask various questions and you can win more trading cards that have codes on them. The Tour Guide will also take you on a few rides/attractions and you won't have to wait in line

When you get home, you enter the codes on VMK and that gets special items for your VMK character

You will end up with a lot of trading cards with codes, by the end of the tour
I think they have added another Quest, of Tomorrowland, since we were there last month. Maybe someone else can add to what I have here. But this is the basic story of the VMK Insider Tour! Have fun!
