Las Vegas is in the midst of its annual travel trade sales mission to Canada, with calls in Toronto, Vancouver and Victoria. At the Toronto event Tuesday, suppliers, retailers and media were invited to meet and greet 19 reps, ranging from mega resorts to coach and flightseeing companies. Among the door prize winners at the luncheon was Dennis D’Souza of Royal Scenic, joined here by Jim Michael of the Fashion Show mall and Rachel Griese of the Venetian/Palazzo.
