Travel for Charity. Cruise for a Cause. As a friend, customer, or partner of McDCG, we invite you to book your non-airline travel here and support a great charity at the same time! Once you book through McDCG Travel, all travel booked here will support Habitat for Humanity. As you may know, McDCG donates 3% of all gross income (not profits, all incoming monies) to charities as part of our commitment to give back in thankfulness for our many blessings. We’ve partnered with GW Travel, a travel agency with a social conscience, to improve our donation rates. GW takes no profit for travel booking – it diverts any profit realized (from hotel, cruise, and car rental bookings) to a worthy cause instead.
