Hi.. I have about 5 days in London and made a mistake by making a booking at Novotel Wembley which is quite a distance considering that I am planning to make a daily trip to attractions in zone 1 and 2. Because I am unable to cancel my hotel booking, I wld like to find out which would be the best and effective cards to purchase for my transportation - Oyster or Travelcards. We are travelling in a grp of 4 and heading there in Nov. Appreciate any guidance n tips. TIA!
