For a referral discount on your first trip with Overseas Adventure Travel or Grand Circle Travel, you can use my name and ID number as a referral. Simply go to oattravel.com or gct.com, and click on Create an Account. When it asks who referred you, enter Graeme Greenhill, customer ID# 2778588.

If it doesn’t offer an opportunity to enter that information when you create your account, you can provide it when you book your first trip.

You will receive an additional $100 discount on your first trip, over and above any other discounts that may be offered at the time.

Full disclosure

• We will also receive a discount on a future trip after you have completed your first trip.
• Unless you change your Email Preferences you will receive emails from Grand Circle and/or O.A.T. announcing new trips and other discounts and price reductions (the savings can be substantial).
