I am installing laminate flooring over the course of several days. Do I need to use the standard 48 hour acclimitization period?
The "48 hour" timeline assumes the flooring cartons are laid out to "acclimate", with air only getting above the cartons.   

Get air underneath them. Take your first day or two's worth of packages and lean them against a wall so air can access them on both sides.   If you want even faster adjustment, bust them out of packages and fan them out individually for a few hours.
