Should I use an orbital sander or a belt sander for sanding a section of varnished floor?
I've got both types of sanders and I use the belt sander when there is a lot of wood to be removed and the orbital sander when the amount of wood to be removed is small. You have a little better control with the orbital sander. With the belt sander, it's easy to put some pretty deep grooves in your work before you know it. I'd go with the orbital sander.
