Hardwood Installation

I Will Be Installing My New Hardwood Floors Next Week. I Realize That No Room Is Perfectly Square And You Need To Compensate For The Unsquareness Of The Room With Your First Cut. But, The Majority Of My Installation Will Be In Rooms That All Flow Together, Ie No Doorways. I Prefer Not To Stop Laying Hardwood Between Rooms In Order To Square Each Individual Room... Any Solutions?
Thanks.
