You arent giving yourself much of a window to fly in, get your bags, trasportation to your hotel, check in, drop your bags, get your wits about you and get to Fort Wilderness. Not to mention you have a deposit on your Hoop Dee Doo, so should you miss it, you will still be charged! Also, Disney is supposed to be relaxing! Try to book for another day and you will be able to better enjoy the experience! If you cant get resses right now, keep trying back, there are cancellations all the time! Good Luck!
