Hi Sandy!
The only way to determine how many days are left in the Keys to the World (KTTW) from your previous visit is to check with the Concierge at your Disney Resort hotel, or with Guest Relations at any Disney Theme Park. Simply present the KTTW and the Cast Member will be able to tell you how many days are left-over, the type of ticket, and its value.
Most guest-rooms at Disney's Port Orleans Resort - French Quarter are within easy walking distance of the resort's main facilities. However, Buildings 2 & 5 are the closest to Doubloon Lagoon, making it an ideal location for families traveling with children. For a quiet room in these two buildings, ask for the second or third floor. Take a look at the resort's map HERE. Buildings 1, 6, and 7 are a moderate walk from the resort's main facilities.
Consider staying at a Water View Room. However, be very specific to request a River View Room. The best views are of the pristine river bank opposite the Sassagoula River. f you are traveling with children, I would recommend Building 5 room blocks 5117-5122, 5217-5222, or 5317-5322. If however, you find yourself traveling without kids, then I would suggest Building 7 room blocks 7141-7148, 7241-7248, or 7341-7348. You may ask for a River View Room in any of these room blocks, but there is no guarantee your request will be met. Cast Members will try to accommodate you based on the resort's occupancy, and other factors taking place at the time of your arrival. Please let me know if I can be of further assistance.
Have a magical stay at Disney's Port Orleans Resort French Quarter!
