New website - RoomerTravel. It's like Stubhub for hotel rooms. Great for when you book a hotel room that you can't get refunded. You can list it here and offer it to another party. The site takes 15%, but at least you're getting something back. If you still want to hang on to your hotel, you can always call the hotel and ask to reschedule your booking for another date. Then later, if you still need to, you can cancel the reservation.
App - MiFlight for iOS. Learn of Airport security line wait times at checkpoints for domestic and international travelers.
