🎓 Students should present a Student Identification Card (SID) with their name and valid dates.

If you’re seeing an AVS Mismatch message during checkout, don’t worry—it just means there’s a small difference between the billing address you entered and the one your bank has on file.
To keep your payment secure, our system follows strict verification rules. Here’s how to fix it:
✅ Double-check that your name and billing address match your credit card statement exactly—including punctuation, abbreviations, and spacing. Even a small difference (like “St.” vs. “Street”) can trigger the error.

Secure payments. Local expertise. Unforgettable experiences. That’s the Gray Line way.
If your payment screen refreshes or you see an “Authorization Error”, it likely means your transaction did not go through, and your tour is not yet booked—especially if you haven’t seen a confirmation message saying “Your booking was a success.”

✅ Double-check your payment info—make sure everything matches your card details exactly.
🌐 Check your internet connection—a stable Wi-Fi network works best.
🔄 Try a different browser—sometimes switching to Chrome, Safari, or Firefox does the trick.
💳 Use another payment method if you have one available.
