I used laminated flooring but would offer these comments. I second the idea of not gluing the flooring down. I would also suggest removing the dinette, coach, and side cabinets and installing the floor continuously under them. Removing them will take less than an hour with a battery powered drill and will make installation 10 times easier. It will also remove the 1/4 round look at the base of the cabinets. When reinstalling the cabinets you can drill a clearance hole through the floor for each screw and allow the floor to float.
