Here's what I did for some ideas.....
What hotels we selected for the guests, with pictures, pricing, ticket information pricing and where you can get discounts. The web addresses to here and alllears to give them some more planning info. Details on the wedding.... where it would be and why we chose it. Where the reception was, and what time they had to be to get the limo. We were there for all the Christmas festivities so I did a page on that. I aslo did a tips page on everything from fastpasses to moleskin to getting a second bun with your double cheeseburger to save money. I also did a packing list and a listing of average weather since we were going in Dec. and I was afraid everyone would think it would be 75 everday. Also park hours, and a discription of what each park is, for while we were there including extra magic, and the firework schedule, as well as what rides were due to be closed that week. Info for kids like child care, pirate cruises, autograph books etc... Information on our welcome party & everyone's names who were going who they were to us and where they were staying (I had an intimate though so I only had 9 people to list). The last thing I provided was a listing of all the extra tours disney offers.
As you can see I went wayyy overboard with mine, especally with only having 9 guests but I had fun with it even if only 2 of the 9 read it.
