The San Diego Union-Tribune did an article over the weekend entitled "Going The X-tra mile: As boutique hotels flourish, they are changing how larger chains accommodate free-spending Generation X travelers."

Pretty heavy tech focus, in that GenXers want wireless access and MP3 players with thier leisure hotel stays.  Plus they like to do more leisure lifestyle stuff that "boutique" hotels seem primed to provide them.

Some mentions of some local hotels: Hotel Solamar (operated by Kimpton Hotels) and the "W Chain" (operated by Starwood) plus for the San Diego area there are also: Hotel Parisi (La Jolla), Prava Hotel (downtown), 500 West (downtown), and Tower 23 (Pacific Beach – opening in June). There is also Morgans Hotel in New York, and Kimpton in San Francisco. 

Only 217 of the nation’s 49,000 hotels are consider boutique but their impact is growing as GenXers are spending on average $1297 on a leisure trip, compared to Baby Boomers with $1155.  Some companies mentioned as making moves to be "cooler" include: Hyatt, Hilton, Marriott, and Intercontiental (operated by Holiday Inn).

NOTE: Sorry for the lack of URLs to some of the hotels.  I ran out of time.
