Save on Hotels.com bookings when you use promo code ROADTRIP45 at checkout, saving up to $45 off of reservations of $300 or more. These hotels are already discounted, sometimes up to 30% off. This promotion is good through 6/12, and is only good for "non-chain" hotels, so no IHG or Hyatts, for example. This is in addition to the discount Hotels.com already has with many hotels, some over 30% off.
