We travelled to Europe with Dpauls in 2015 and just returned yesterday. It was Italy, Switzerland and France. We did not book Gandola ride before while in Venice the tour Guide Mr Amit ask us for 100 euro person but we did not book with him. The same thing was available in 20 euro per person at Venice. The tour guide was more interested in making money for him (or company). I agree to Mr Sweet (see comments above). Whole trip you will be travelling in the bus and will be given only half an hour to shop and that too if the tour guide is in a good mood. They will treat you like poor people. The poor Indians who want to see the world. One day breakfast in Paris was leftovers by another group which was not even replenished. Next day when complained, it was done properly.
He arrange night trip to Paris by his own and making money. I think we should inform D Pauls about his activities.
