We are going to lay some vinyl plank flooring throughout kitchen, living, through to and throughout the sun room. The trickiest thing we see is there is a kitchen island to work around and the stairways. What is the best way of laying this out so that the two sides meet once you work around these obstructions? Hope you understand what I mean and I appreciate any feedback.

I have 800 sq ft of 1/2" locking solid stranded bamboo floor on its way and I'm trying to decide between floating and glue. I'm doing every room on my 1st floor (see attached pic), except for the powder room and adjacent W/D area. The flooring will run lengthwise from one side of the house to the other, if that makes sense. The longest length of a single span is 30' from "front" of dining room to "back" of living room, and 30' from the garage entry to the far (right) side of living room. We are installing over a wood subfloor (I assume OSB, but I have yet to check). My concerns for floating are: hollow sound (I wanted solid h/w, nailed down), expansion issues (I don't want to use T molding), and dealing with 2 stair transitions (2 steps down from front entry into living room and the top edge of the basement stairs off the living room). My concerns with glue down are: slow/messy install (and hearing about it from my wife, who wants to float), difficulty of removal (although I don't plan to), and I guess that's it. I mainly want to know how concerned I should be regarding expansion issues if I do a floating install? Between the pinch point(s) heading into the kitchen and the somewhat long length of some of the spans, will I be able to get away with not having expansion joints (aka T molding)?? I'm in CO, where it's very dry but I have a house humidifier and plan on keeping the house around 40-50% RH. I consider myself quite competent at recreational home improvement and am not worried about the difficulties of executing either install...I just don't know best practices when it comes to this stuff.
