Part of this consideration is the price per night for the room. But how do you find that, when the site always gives you the package price? I'll show you!
Go to the Disney World website https://disneyworld.disney.go.com.
Put in your travel dates, number of guests, and resort in which you are interested. Click the green View Rates button on the right side.
Next you will be presented with information regarding that resort's option. Change the radio button to reflect "Room" and you should get something that looks like this:
Under the price, on the right hand side, there is a blue link that says "Rate Details" just above the blue Select button. Click on that link and you will get a screen that looks like this:
If you are pretty sure you want to travel around the dates originally provided, then you can use the arrows on the right and left to move the dates forward and backward. This is an easy way to look at the price differences for weekends versus weekdays or even what the following or prior week's prices are.
If you are really open on your travel dates, you can click on the blue link on the bottom left "View Rate Calendar". This will show you the per-night prices on a calendar. Again, you can use the arrows to move forward and backward in time.
To go back to the prior window, simply click on the blue "View Price Per Night" link on the bottom left.
I hope this helps to give you some different options for reviewing room rates. If you have questions or comments, please put them in the comments below and I will get back to you.
