A number of websites offer information on hotel availability:
quickbook.com is a useful resource for business travelers where a range of hotel deals can be selected based on lowest prices, also has hotel reviews
www.HotelRooms365.com could be worth another look or hotel.com may also be useful
Good old Expedia.com and Orbitz.com can be useful for booking low-cost flights or you could go straight to the discount carriers such as Southwest, AirTran or JetBlue. Many websites also offer email alerts to let people know of specials and promos.
