The trips back home will be nice and you can treat the visit from your wife as kind of a mini-vacation (but where you have to continue working during the week.
My wife had to go out to Maryland during the summer for 10 days, for work. We have 3 little kids & they got her a hotel room with 2 queen beds & a rental car, so I said hell with it. We all went. I lucked out and didn't have to work too much while out there, which made it a heck of a lot more fun for the kids.
