What people love about 4 Week Thailand, Cambodia And Vietnam Tours
- Ultimate South East Asia (27 Days, Intra Tour Air Phnom Penh To Siem Reap)
My Contiki tour in Southeast Asia with Lisa was beyond amazing! She was such an incredible your guide! She made it her goal to include everyone and make the trip as fun as possible, thinking of games to play on long journeys and checking in on everyone along the way. She was also really knowledgeable of each area we visited and if she did not know the answer to a question one of us asked, she made sure to go and find out for us. She was really respectful of the areas and the people we visited and was always a good laugh, making my Confiki experience 100 times better!
