We have already had a large number of sales from these offers, and expect to get even more.
On a different subject, we have an exclusive offer from Port Aventura in spain, we currently have all their tickets on sale at upto 50% off normal web prices. This offer is only available through AttractionTix, so every other company is significantly more expensive than us. The offer is exclusive to the end of this month, and will run to the end of march. You are free to advertise this offer on your websites.
