We will be in London Aug 15-20. I am wondering what tour attractions need to wait in long queues to get in, and is there any way to avoid the long queues (such as buying advanced tickets)? We plan to visit Tower of London, British Museum/Library, National Gallery, Windsor, V&A museum, War Room, etc
Also, we arrive around 6pm Aug 15, and leave in the afternoon of Aug 20. So in this case, should we buy Oyster card, or TravelCard?
Should I buy Oyster or TravelCard for my kids (12 and 14 years old)?
We will be staying at Premier Inn Kings Cross (at York Way), is there a double decker bus nearby the hotel? My kids want to take the double decker at least once.
Thank you all very much!
