Another tip...look online for discount promotional codes. When booking a hotel for a recent vacation, like the linked article mentions, I found that booking the room directly on the hotel's website was actually cheaper than going through Orbitz or Expedia. I also noticed that the hotel's site had a box to enter a promo code. A online quick search revealed a 20% off promo code for the hotel I was booking. I entered the code and saved an additional 20% on 7 nights in a Waikiki beachfront hotel, which saved quite a bit of money.
