Besides having a hard time drafting our London itinerary, there's another issue that put me in a quandary; deciding the best way to get around the cities. Here, I listed out my public transport dilemma:
CDG Airport to Paris city
After negotiating the maze that is CDG airport, this will be the next milestone for first time visitor like us. From what I read, there are three popular methods used by travellers to get into the city (and vice versa).
By taxi: Taxis can be easily found outside the terminal building. The good thing about taxis is they deliver you right in front of the hotel. But, taxi is expensive compared to other modes of transportation. According to this site, a single taxi ride from airport to the city is estimated to be around 40 to 50 Euros. We will only use taxi if there's no other options.
By bus: The Roissybus has pickup points at every airport terminal. Single fare cost about 10 Euros, and it take an hour to reach the city. Bus departs every 15-20 minutes. It shuttles passengers between CDG airport and Opera district in Paris. Another option is the AirFrance bus. Since our hotel is located quite far from the bus city terminals, this is not the best option for us.
