Do not disturb!

Swanky hotels in Manhattan are renting rooms for short chunks of time in the afternoon — offering randy couples an upscale alternative to seedy hourly motels.

Guests are booking “day use” rooms — often from 11 a.m. to 4 p.m. — at boutique hotels like the Flatiron Hotel, The MAve NYC and Off Soho Suites over the new site Dayuse-hotels.com.

The service costs $120 to $150.
