Small-group tour operator G Adventures is giving travel agents some “G-Normous” perks and prizes in a 4-month campaign running now through April 30, 2018.

Now in its fifth year, the G-Normous campaign offers travel agents a variety of incentives. For the month of February, that includes an extra 2 percent commission on sales made throughout the month using the promo code GNORMOUS in the company’s Sherpa system.

In addition to this month’s increased commission, each booking on a G Adventures tour will earn travel agents one ballot in the weekly prize drawings, plus a booking on a National Geographic Journeys with G Adventures trip will earn them two ballots. Agents booking private group tours will also have the added incentive of the chance to win $2,500. The agent who books the most private group tours of eight or more clients will receive the cash prize. At the end of the campaign, the overall top-selling agents in the U.S. and Canada will each win a $5,000 “G-Normous jackpot” with two runners-up receiving $2,000 each.

But the chance to win prizes doesn’t stop there. Monthly trips will be awarded to the agent with the highest number of clients booked (minus airfare), and first-time booking agents who book more than two clients are eligible for a monthly random drawing to win $250. In addition, any agent who books more than 10 clients will be entered in a random draw to win $1,000 cash.
