I have read some of the old items on Oyster card and believ I
understand it.

On upcoming 10 day visit I assume it is best deal to travel daily in
Tube and Bus sytem in London.

We will rent car for three days and drive around outside London but
otherwise plan to use Tube most of time including trip from Heathrow
upon arrival.

Couple questions. We are staying in Bayswater and will probably only
be traveling in downtown Tourist type areas most of time after we get
from airport.

Is the card really best way to go? Just arrive and get one at
Heathrow? I don't mind losing the card deposit.

How do we pay after initial purchase? Do we just add to it with
credit card at any station?

Anything else we should consider.
