It happened just this this morning -  see https://www.ytb.com/rxmhiebert where you can book trips, car rentals, vacation packages, cruises and hotels. Not only that, start a business that has huge potential.  I should clarify, this  booking resource has been  going full blast for several years - but wife & myself just signed up this morning. Booked a couple of trips to make sure it works.
