How to best to re-coat a polyurethane, oak, manufactured floor?

Answered
The floor has been in the house for some 30 years and the coating is worn in spots, especially around the kitchen area. Would like to save it. It is .125 of an inch thick. I cannot hire anyone to sand it down because of the thinness of the veneer. I was thinking of getting a small sander and lightly sanding and then put on new coating.
Are there any suggestions out there? Has anyone done this before?

    you need to clean the surface and take a fine sand paper and sand the poly to rough it up so the new poly will adhere to the surface

    I did this with a small rotary sander and a high number grit paper. 220. Then I just painted on the new poly (whole floor). Make sure you wipe it down with something damp and let it dry before use the poly. And NO PETS in the area. The sander threw a bit of dust, so if the area is small, do it by hand to lessen the mess.
