If we run them parallel then the hallways would have short planks laid crosswise which we think would look ridiculous. I agree. Floor should be solid before you lay LVP. Floor joists shouldnt affect results in my opinion. I would lay them the length of the hallway and continuous with that direction for the rest of the space for cosmetic purposes as you mentioned. It will look odd if done incorrectly. You could also consider transitioning at the hallway if you wanted to, running the long way in the rooms continuous then gluing down the planks at the transition and running the planks the long way down the hallway.

We had Johnson Hardwood"s Luxury Plank Vinyl flooring, Public House- whiskey sour installed by the builder after we looked at the product at a flooring center recommended by Johnson. We have lived in the house for exactly 2 years, and for the first year the flooring cleaned up nicely. In the beginning, I had contacted the "technical rep" for Johnson, and he recommended Rejuvenate LVF cleaner as it is low Ph. That is the only product I have used on the floor since we moved in. We loved the floor so much that we paid $7000 to have it installed in our lanai last year. In the past several months, the floor in the main house is blotchy or spotty throughout, and it looks like certain areas have a film. We clean up water and spots immediately, but the spots continue to show when the floor is wet or dry. So far the lanai doesn't have the same problem, but it's only a year old now. I did report these issues to the technical rep at Johnson, and he wants we to contact the maker of Rejuvenate as that product is likely the cause of the spotting all over the floor. He also wants me to find out who the contractor bought the flooring from when the house was built, and I am to provide the name and contact info for the flooring contractor who installed the floor in the lanai last year. I have tried to take photos with my iphone, but only a few of the spots will show up. I clean this floor at least twice weekly with the Rejuvenate and I vacuum it daily as everything shows up on the dark floor. I know I am going to get the run around from the Johnson rep. I am so upset that we paid top dollar for what we thought was a quality flooring only to have it look like cheap vinyl flooring. I wish we had never heard of Luxury Vinyl Plank flooring.

We ended up switching from an LVP to Mohawk RevWood Plus, which is a laminate that has a “WetProtect” lifetime surface and subfloor waterproof warranty, maximum scratch protection, and a lifetime “All Pet” warranty against pet stains. We are SO happy we decided to switch from LVP to this laminate, for a couple of reasons. We are still getting the water protection benefit of the LVP, while also getting the durability of a higher quality laminate, and for less money. Another huge plus, in our opinion, is that the “grain” in the surface of the laminate is visual without being abrasive. The Paradigm flooring was actually rough enough that I could not run a dust mop across the boards easily, only in the directions the boards were laid—which isn’t always the most convenient way of doing things. The laminate is enough smoother than this is not an issue, and is also MUCH more comfortable on bare feet, and gentler on socks and the knees of our little grandies crawling across it. Just my $0.02.

@clubnev Thanks for the info! Hot and humid here in Houston as well especially when power goes out. I finally ponied up a did a whole home generator to avoid being out of power around hurricanes and freezes. Did you notice that when your whole First Crush floor went in the flooring warmed compared to sample boards or laying out a single box? In certain areas of my home samples/sample boards will grey up in the day with certain natural light, but at night under 2700K lighting.... Wow...perfect light brown floor with no wheat, yellow, gold, or orange.
