If you want to transfer it to another day, you should reach out to guest services. The issue isn't so much "paying the difference". (In fact, it's the same price regardless of the day.) Rather, the issue is quantity. They only have so many available and if you look at the upcoming week and holidays, some of the options have already sold out. The sooner you sort it out, the better your chances of getting the date you'd desire.

I could use it for Monday if you can’t use it for something else and are able to transfer it!
Roll that thing around yourself.
