As most of us know, the reduced number of travelers in lounges also reduces the ambient noise level. But many—like Delta Sky Clubs
—now have quiet areas or "relaxation zones" for those looking to nap, read or type away at their laptops. True, most lounges charge hefty day fees, but the cost may be worth it if you're stranded (missed connection, anyone?) for the entire afternoon. Check Groupon
and Living Social
for discounts, and before you shell out your hard-earned cash, download Priority Pass
, a free app for iPhones, iPads, Androids and BlackBerrys. It uses GPS technology to locate the nearest lounge and provides details, pictures and ratings, letting you get the most silence for your investment.
