INVITE A FRIEND TO EXPERIENCE CROSS-BORDER FRIENDSHIP For ISIC students, friendship doesn't stop at national borders. Because we strongly believe in cross-border friendship, we regularly come up with exclusive 1+1 privileges within our international community. We encourage you to invite a friend - a mate from across the border, or just your best pal from next door, that's up to you - purchase a unique experience and get one for free. Because 1+1 is more fun than doing something on your own. Which 'Invite a Friend' 1+1 experiences are we talking about? Just a few examples: 1+1 on the best rated tour of Flanders Fields in and around Ypres 1+1 on weekdays first class volleyball and football matches Category Invite a friend
