Cheapest way to get to Bellingham Rd and back on Tuesday. Is it worth getting a visitors Oyster Card just for a one day return trip? I plan on walking to Victoria Bus terminus and getting the 436 to Lewisham and changing to the 136 or 298 to Bellingham Rd. I would like to do the same coming back an hour or so later. I see something on the London Transport web page about a fare cap which would be good. What do you think...a £5 oyster card?
