cool,
meese!
I'd personally try every method possible with the equipment you have now...you can run the cords under carpet, etc...but at some point it'll be time to reconsider wired vs. wireless.
I live at home (for now, till I get a job) and I have two puters I'd like to network. the only open phone plug is in our basement, and my bedroom is on the 2nd floor. I've given up trying to route the cables upstairs (my dad tripped on one) and I can't afford wireless now. so I'm here in my basement with my two networked puters on the same table, using a KVM switch.
I know this doesn't help you much, and I"m sorry, but I would like to reiterate this point: if wired causes you much consternation, try going wireless to a switch in one of the childrens' bedrooms, and run a cord across the hall to the other...so you're not left with a pile of unused stuff. you could always use wireless from your sunroom to the switch in the bedroom part of the house, and have it wired there. minimize your interference.
