For a value resort, I would suggest All Star Music as it tends to be just a little quieter. Ask for a quiet room location too!
You'll want to be sure to phone in your Advance Dining Reservations at 180 days prior to your September trip. So be sure to draft your itinerary and see which days work best for dining at the restaurants that you are interested in. Michelle explains the deluxe dining plan
here. Since you are on a budget, you might prefer to get the basic dining plan and eat light for two meals per day. Remember that time spent at table service restaurants takes away from touring the parks.
A good time for visiting Fantasyland and ToonTown in the Magic Kingdom is during a parade, fireworks or in the hour prior to closing time. This will allow you and your hubby to really enjoy these areas.
Make sure to enjoy a character meal!
Keep planning and your trip is sure to be memorable.
