Hardwood to Laminate floor transition
The biggest issue will be the height difference from the hardwood to laminate and a moulding to cover the transition.  Depending on the height of the hardwood, you are at least looking at a half inch difference (at minimum) between the wood and laminate.  And the moulding might also be a trip hazard for any older people as they enter/leave your house.

My personal choice would be to remove the section of hardwood to remove the above two issues.
