Tour Guide mike is DA' BOMB!!!!!!!!!!!!
I have been to WDW so many times I don't even use any park maps anymore.
However, I love, love love love love love love love love love LOVE his website. Seriously. Can't. Be. beat.
I would never in a million years ever go again to WDW without planning a trip at his website. There is a load- ton- humongoid- amount of info, though, so at this point in your planning stage, with the wedding and all- I don't know if it would be worth it to you to register. It might take too much time to look at everything and you have so much to do, I don't think it would increase your trip at all.
The best time to use him is when you are planning a trip a ways out. I never make any ADR's anywhere until I have his best days-which parks info. Then I plan which parks to go to, based on the ADR's I have that day. Easy- peasy. And he is always dead on. Unbelievable. I like to try to guess what he is going to say before he posts which days to do- I make a tentative plan. Then I will regroup after he lists them.
Also, his forums and the people that post there are awesome. ( Hi NC!!

) So many people willing to give you plans, look at your plans, critique, tweak them, oh and the touring plans that I print and take to the parks...
The info there is, I think, a lot more detailed and you find out secrets that most Dis'ers don't necessarily know. But you have to promise not to talk about them on any other website. Which KILLS me, b/c so many times I have wanted to share so many things with the MAYers, and couldn't. I have PAGES and PAGES printed out of info he gives you- hints, plans, where to stand, which line to get in, which side of certain rides to go to, best places to sit to watch parades, and fireworks- pictures that are amazing, detailing "secret" entrances and exits...

Things you'd never even know were there and many people walk past them everyday...
You get the idea. I am a TGM groupie. Love him. Best money, IMO, I spend on the entire trip.
YMMV
