Hi, Jennifer!
Let me see if I can help clear up any confusion you have about the
water transportation available from Disney's Contemporary Resort.
There is a boat launch at the Contemporary and that boat travels to Fort Wilderness and Disney's Wilderness Lodge where you can then transfer to another boat that will take you over to Magic Kingdom Park. There is not currently a boat available that will take you from the Contemporary directly to the Magic Kingdom. Of course, please keep in mind that things are always subject to change depending on any construction that might be going on and things like that.
One of my very favorite things about staying at Disney's Contemporary Resort is having the ability to hop on the monorail that will whisk you right over to Magic Kingdom Park! I absolutely love the view from the monorail! It's a definite "must-do" for my family on each trip! You can walk over in about 5-minutes as well.
On another note,
Disney's Grand Floridian Resort & Spa happens to be my very favorite Resort hotel in the world! My husband and I honeymooned in a tiny little Victorian town over 20 years ago and whenever we walk onto that property, it brings us right back to that moment so long ago. It's truly a magical place!
I hope I've cleared things up for you, Jennifer! Please don't hesitate to write in again if we can help with any other questions you have.
Wishing you Pixie Dusted vacation planning!
