Installing laminate on a sound substrate is a piece of cake. Make a pattern or not, depending on the installation, dry fit, leaving an overhang wherever possible, apply contact cement according to the instructions on the can, let it dry, use sticks, kraft paper, etc. to keep the laminate off the substrate while you position it, then remove the sticks or kraft paper to allow the laminate to bond to the substrate.
Then apply pressure with a laminate roller to remove air bubbles and insure good contact.
Use a router and a laminate bit with a ball bearing roller to trim the laminate and a laminate file for areas the router won't reach.
I recently installed laminate on my boat on the vertical surfaces under the seats where I removed the original carpet.
There are several videos on youtube.com showing how to install laminate.
Or hire a pro!
