Flooring – Should I run laminate continuously through rooms, or separate with T moulding

I am installing laminate flooring in an area that has two bedrooms and a living area. The bedrooms are about 150 sq ft each and the living space is around 250 sq ft.

I know about the standard spacing that must be left between the flooring and the walls. I also understand I should run flooring parallel with the longest wall. I would like to know if I should just run the entire flooring from room to room, or if I should separate it based on the rooms and have T moulding to transition from the bedrooms to the living space. I think this would help with the expansion of the flooring and be less likely to have bowing. I think it would look better to have no spacing at all, so maybe I'm being paranoid about the spacing/bowing. Is there a standard for this type of transition? I think once you reach a certain square footage you need to insert a gap, but I'm not sure what that is. Any advice is appreciated.

I think you should be more concerned with the expansion gap than other types of expansion.

In my opinion you should use some kind of separation between the living room and the bedrooms, because bigger rooms require bigger expansion gaps. And that difference in expansion could give some bowing.
