Airports are coming up with more ways to entertain you during increasingly long layovers.

In an effort to reduce the stress of holiday layovers and lost luggage, Bush International Airport in Houston is setting up karaoke booths to help frustrated travelers unwind. Yes, karoke! AP reports small prizes will even be awarded to singers. (If this does not sound like fun to you, consider packing ear plugs and Tylenol in your carry-on bag, stat!)

But if you're not into singing Barry Manilow covers, never fear. Karaoke booths are not the only entertaining activity to be found in airports these days. With a little research, you can uncover other hidden delights of being trapped in a giant building with gray carpet (that don't involve stuffing yourself with Cinnabons).

Massage Bar: Several airports offer massages. Going through Nashville, TN, check it out on Concourse B or C. For a complete list, click here.

Airport Gym: We know a workout isn't a massage, but if it gets you a break from the kids for a little bit while your husband feeds them, fine! Dallas/Ft. Worth boasts several gyms. Click here to find more airport gyms.

Manicure/Pedicure: Don't have time to get your nails done before packing up the family and heading to the airport? Do it on your layover! Tons of airports offer manicure and pedicures including JFK, which has several several XpressSpa locations throughout the terminals.

Bar: It's plain, simple and located in almost any airport. If you can only convince your husband to be alone with the kids for a few minutes, run and get yourself a nice stiff drink.

But if your husband refuses to be alone with the kids during the layover (and who can blame him?), here is a complete list of things to do with your kids, from museums to play areas:
