Over-50s specialist Saga has unveiled its Escorted Tours brochure for 2018-19, and guaranteed departures on all itineraries.

As part of the launch, agents can win £50 in lifestyle vouchers in weekly prize draws.

Eleven of the tours are new, including Gorillas of Uganda, Ionian Island-Hopping and The Great Indian Rail Journey.

Iain Powell, Saga head of trade sales, said: “One of the pinch points for agents and customers alike is when operators cancel tours due to low numbers. We’re conscious this can have an impact on the relationship between the customer and the agent, and can also lead to both being more cautious about booking with that operator again.”

Saga’s 11-night Gorillas of Uganda tour features treks through Bwindi, Kibale and Queen Elizabeth national parks with the chance to spot chimpanzees and rare tree-climbing lions, a Mount Rwenzori hike, six-hour scenic drive to Lake Mburo National Park and a cruise on the Kazinga Channel. Prices start from £3,799 departing Heathrow on selected 2019 dates.

A 13-night Trekking in the Himalayas tour marks 65 years since Edmund Hillary conquered Mount Everest. It includes a Buddhist llama blessing, and visits to Kathmandu and the valleys of the Annapurnas. Departures from Heathrow or Manchester run from October 2018 and November 2019, with prices from £2,499.

To mark the brochure launch, agents making any holiday, cruise or river cruise booking by August 31 will be entered into a weekly prize draw to win £50 in lifestyle vouchers. Twelve winners will then be entered into a final draw to win a 10-night private tour of Sri Lanka for two, flying business class with Emirates. The winner does not have to be over 50.

Powell said: “The touring market is growing significantly and agents have been pivotal in selling these products for Saga.”
