For travelers who just want to party, there are some new online travel agencies that focus on the hottest clubs and concerts.

WantTravel.com, a division of Track Entertainment, a media and lifestyle company in New York, allows travelers to pair flight, hotel and cruise bookings with music, comedy and club events. It says it is aimed at 18-to-35-year-olds. Click on Clubs and Nightlife to link to its sister site, Clubplanet.com, to register for the guest list at clubs.

Stuff, a men's lifestyle magazine from the publisher of Maxim, and Key2Travel, a luxury concierge service, recently teamed up to create Stuffviptravel.com. The site, which bills itself as a concierge service for "the ultimate bachelor experience" and features photos of scantily clad women, offers concert tickets, V.I.P. entrance to nightclubs and testosterone-pumping vacations like river rafting and off-road trips. The vacation packages offer airline and hotel options. One nifty feature called the Stuff Party Planner makes arranging a bachelor party easy by letting you plan your itinerary and invite friends along.
