I used tiles to do the floor in the master bedroom. The floor tiles have several problems. They require luan to be put down first to be glued to, that takes a lot of time and increases the price quite a bit. They stink, literally they give off a bad odor for months (currently over 6 months), stop and smell a box of floor tiles at the store before buying them! And last of all we moved the bed and there are permanent dents in the tiles where the bed had been.
So for the living room floor I used the Interlocking laminate - wood looking floor tiles. It took 8 hours to do a 200 square foot floor. The first 2 rows are the hardest to do. When you tap in the next row the first one wants to come apart. Then the lip gets into the groove so they do not go back together. The floor is supposed to float, but I was tempted to nail down the first row then take the nails out after the floor was done. Anyway if you can get the first 2 rows done then you can stand on them to do the rest of the floor.
You might want to know that even though they easily snap together one at a time, when you have a row of 18 feet of them they do not go together very well at all. You will need to get the tool kit to gently tap them together or make a tapping tool out of a 2x4 about 8 to 10 inches long by cutting a groove it it to match the groove in the floor tiles. Also you need to keep each row slightly raised up (Put a pry bar under the leading edge to do that) until they are all snapped together lengthwise. That allows some of them to unsnap slightly so they need to be tapped back together. When they are gently tapped together they will then drop down to be level.
Hopefully soon I will have before and after pictures. This one is a before for sure!
