While the Girls are Away: Bedroom Redo

My "big girls" are spending a couple of weeks with their "Mims and Pops" in Texas, so I thought it would be a great time to surprise them with a room redo when they come home.   Currently, they have matching twin beds that are oriented in an L shape - not ideal or pretty.  They've been wanting bunk beds, and since it should help open up some floor space, we caved.

At the risk of going all-out girly girly, I'm planning on a (very light) lavender striped wall to coordinate with the Biscuit bedding that's on order.

Where I'm a bit stuck, though, is on rug selection.  My natural tendency is to over-match, so I often have to step back a bit to choose something that works, without looking too much like a furniture showroom.  I've put three variations into design boards to get a feel for what will look best.   I've ordered marquee letter lights in each girl's initial, but unlike the images, the letters will be gold.  

So, in general, a lot of softness going on.

My first choice is probably this loose floral rug that pulls in the lavender, but also gives me some wiggle room to accent with other colors.

Another option is this more "matchy" overdyed, low pile.

Then there's the wild card.  Offering a more high-contrast look, while still pulling in the base lavender.

Thoughts? Opinions?  Give 'em to me.
