Dear Joe:
I must assume that the travertine tiles are not polished, but with a hone-finish. (That's how they typically sell Turkish travertine tiles at the HD.)
The sealing of hone-finished travertine is optional. It does not offer any protection to the surface of the stone; it only helps to prevent imbedded staining, which in the case of travertine is a rare occurrence. If it were my own home, I would apply a good-quality impregnator like MB-4 only if the floor was in a kitchen.
