Welcome to the camping board!!

Upon check-in, you will be loaded down with lots of material for you to read and learn all things Disney. But just some quick transportation info for you regarding FtW...
Points of interest inside FtW....there is an internal bus system that goes to all loops and recreation areas. Basically....the purple line serves the west side of FtW, the orange line goes directly up the middle, and the yellow line serves the east side of the campground. All routes go from the Outpost bus stop to the Settlement bus stop.
To go to the Magic Kingdom & Monorail... Take an internal bus to Settlement Depot and walk NE to the Marina. The walk is less than 1/2 mile. There are two boat options. (1) Go to left side of dock and wait for the boat that is devoted to the Magic Kingdom. This boat usually stops at Wilderness Lodge to pick up guests. If you want to wander around the Lodge, go ahead and do so. (2) Go to right side of dock and wait for a smaller launch that goes to the Contemporary Resort first, and then circles around to the WL. To get to the monorail, get off the boat at the CR, go to the monorail level inside the resort. This monorail stops at: Stop #1: Ticket and Transportation Center - where you can board a separate monorail that goes non-stop to Epcot. Stop #2: is the Polynesian Resort. Stop #3: is the Grand Floridian. Stop #4: is the Magic Kingdom. Then you return to the Contemporary. You may exit and re-board the monorail at all the resorts. No one will stop you and question why you are there. This is a fun way to resort hop - just get yourselves All You Can Drink Mugs at FtW and take them with you. You can use them at all the resorts.
To go to other resorts and Disney Parks... Take an internal bus to the Outpost Bus Stop. There are direct buses to Epcot, Animal Kingdom/Blizzard Beach, the Studios, and Downtown Disney/Typhoon Lagoon. To get to the other resorts (other than Y&B & Boardwalk), you can either go to DTD and catch a resort bus directly to the resort you wish to visit. You can go to any theme park and catch a bus directly to the resort you wish to visit. There are no resort-to-resort buses.
If you get confused or mixed up while at Disney, just ask any cast member for help. You will never get stranded or be lost for very long. My biggest piece of advise is this: if you are relying on bus transportation to get around, allow yourself at least 45 minutes to an hour to get where you are going.
Here's a link to a map of FtW. The cabin loops are 2100-2800. I hope this helps you!
