Hotels are easy--just get in touch with the hotel and talk to the FDM or GM and ask them what they can do to match an online price you're about to book that you found. Hotels pay up to 20% in commissions for OTA or even central reservation booked reservations, so booking direct saves them a serious chunk and they will gladly match the price since they save that 20%. At least this was how it was up to 2015 when my family finally left the industry.
