People often do things in hotels that they would never do in their own homes, such as sleep soundly, watch Marley and Me, or let the kids drink as much shampoo as they want. Let loose with today's Groupon: for $42, you get one night in a double or king room and $12 worth of breakfast at The MET Hotel (a $113 value) in Troy.

The C-shaped MET hotel, originally built to host Chrysler's corporate offices, houses 191 rooms, 106 of which are balcony-bedecked, and resides on 18 lush acres near local shopping centers and sports arenas. Designed with comfort in mind, each room comes equipped with everyday essentials such as an irons and coffeemakers, as well as desks replete with an ergonomic chair and complimentary WiFi. Wage war over the remote control, capable of controlling entertaining options such as cable TV, HBO, in-room movies, and robot prop comics.

This Groupon also gives guests $12 worth of breakfast to fuel mid-morning laps in the hotel's indoor pool, squat-thrusts in the gym, or sweat-a-thons in the sauna. Shoppers will delight in the nearby Somerset Collection, which flaunts more than 180 stores, and whether it’s the season for pigskins or pucks, all of Detroit’s sports arenas are just a short drive or catapult's throw away.
