This offer cannot be applied to existing bookings and cannot be used in combination with any other promotion or discount offer. Viator Gift Certificates and Walt Disney products are not eligible for discounts.
Hopefully useful for people planning to travel over the Christmas break and were planning to book something on Viator anyway. As always, disclaimer applies: do your homework and check to see if other travel websites offer the tour/ticket cheaper anyway.
Looks tempting!
