My 10 year old daughter and I will be in London 4-7 May, landing at Gatwick in the evening from Stockholm, then staying at a hotel near Acton railway station. I have found a route from the airport to the hotel. When traveling around London during these days to and from zone 3, we shall also visit the Harry Potter studio.
Would it be best to get an Oyster Visitor pass or an Oyster pass?
And in the queue to get the Oyster card at the airport, are many details needed when buying the different cards?
