In working on a story for NBCNEWS.com about hotel booking sites trying to stand out by offering a twist – including Winston Club, which plans to match people up to share top hotel rooms – I discovered a good resource for travelers who find themselves stuck at the airport.

HotelsbyDay.com is a site that helps travelers find good rates for short stays at hotels during the day.

These aren’t the, ahem, one-hour or less kind of stays. The service offers stays of at least four hours in three-, four- and five-star hotels, enabling a traveler to rest and refresh before or after a long flight, get some work done in a quiet and comfortable space between meetings or, perhaps, for a family to have a “daycation” at a hotel with a pool, waterpark and spa.

The site has a search option for airport hotels and on that list you’ll find the Miami International Airport Hotel (located inside the terminal) – offered during my search for $55 for a four hour stay between 10 a.m. and 5 p.m. – and the post-security Minute Suites – DFW, offered at $100 for a four hour block between 7 a.m. and 11 a.m., $110 between 11 a.m. and 3 p.m. and $120 between 3 a.m. and 7 p.m.

I called to check and compare walk-in rates as was told there is not a posted rate at the DFW Minute Suites for a 4 hour stay, but that, with taxes, a 3.5 hour stay would cost about $134 and a 5 hour stay, $148. So the HotelsbyDay rate does indeed offer some savings.
