Specialising in escorted tours, Travelsphere says it has guaranteed more than 800 departures across dozens of destinations with the launch of its latest holiday collection.

For 2018, it has added new experiences in the Galapagos, Norway, Iceland, Switzerland, North America and the Aeolian Islands.

Every Travelsphere worldwide holiday booked before July 31 will include free door-to-door VIP private airport transfers for passengers living within 75 miles of their departure airport.

Agents can also offer savings of up to £100 per couple on selected early European bookings and £400 on selected early worldwide bookings.

Alastair Campbell, Travelsphere managing director, said the operator had guaranteed departure on every European holiday in its new brochure, which includes more than 20 “unique” tours in Italy alone.

It also guarantees price matching on identical packages offered at a lower rate elsewhere and an extra £100 per person towards future bookings in the event of a match.

All Travelsphere holidays include flights, including from regional hubs, local transfers, accommodation, tour management and local guides.
