We recently took a Thomas Cook Hallmarks tour to Europe.
Having gone by SOTC to America last year and had a horrible time before the tour. The people in the SOTC Chennai office were inefficient and rude - not taking calls, etc. But the tour manager - Tejaswini Padhe - was wonderful. She knew America like the back of her hand and became a good friend.
When we met our new tour manager - Manish Kabre - we kept comparing the two - initially. But by Day 2 Manish, his sense of humour and the rest of our tour companions made the trip memorable. Thomas Cook is the best in Europe. Our schedule was packed, we were begging for rest, but on the whole it was a fabulous experience. We saw and did a lot, stayed in good hotels(except one - the Wiesbaden Ramada in Germany). The food was repetitive, sometimes too oily but always hot.
I would recommend Thomas Cook Hallmarks to anyone who wants to see all of Europe before they decide where they want to go back. We want to go back to every single country, especially Nice, Monte Carlo, parts of Switzerland and parts of German.
