Walt Disney World Resort
You would think you asked an easy question. Disney has made it a complicated question. Hopefully you can view the link above. They now have pricing on which day of the year you attend. In March they have a few different prices, based on which day you attend. All prices are before taxes. If you know which day you will be attending, you will be able to determine the 1 day price. Their standard price is said to be FROM $109.00 a day plus tax.
