Experienced Tour leader escorts your group in accordance with the tour itinerary.
Escort clients, performing meet & greet, assisting clients, regulate and manage the
timing of a group, ensure the presence and involvement of the participants, verify and
confirm facilities and services, provide and explain the travel program, make sure that
the group works in harmony, provide information on the places you intend to visit,
manage any excursions, buy tickets for tourist attractions or means of transport, manage
reservations with restaurants and accommodation facilities, resolve any problems that
may arise during the tour.
So a professional tour leader is not a guide (and cannot therefore provide strictly historical
explanations in the specific places), but can provide general information of any kind, and
give the most complete assistance to customers while staying with you.
