Air Canada Vacations (ACV) is offering travellers heading to Mexico and the Caribbean peace of mind with its PriceGuard program. According to officials, the program was such a success last year that it’s returned with even more hotels. With PriceGuard, if the price of an Air Canada Vacations’ Air, Hotel & Transfer package drops before travel, customers can contact ACV and be refunded the difference of up to a maximum of $800 per couple. This offer is valid for travel from Nov. 1 and completed by April 30, 2014. The PriceGuard program offers a selection of 125 hotels, with 29 new this year. Participating hotels include Sandals and Beaches properties, featuring the new Sandals LaSource Grenada. Clients who book a vacation package with ACV by Oct. 31 will save $400 per couple and $600 per family to Mexico and the Caribbean. Members of the Aeroplan program can earn a valuable 3,000 bonus Aeroplan Miles per member as well. (
