Hello all, I understand the difference between the pay as you go Oyster Card and the "Paper" Travel card. But I'm a little confused about the variation offered for purchase. For instance,
a. what's the difference between a local Oyster Card and a Visitor Oyster Card?
b. What's the difference between a paper travel card and one that is loaded on an Oyster Card?
c. as a solo traveler, does it matter in what form I get the travel card/Oyster Card? Any advantages?
d. Any advantages of buying the TravelCard/Oyster Card ahead of time?
