The best ticket would be a normal Travelcard, it'll save a great deal of
faffing around for minimal extra cost.

It appears that Ulrich is looking for a cheaper way of doing things.
An off-peak Day Travelcard from Watford Junction costs £13.50. The off-
peak Oyster PAYG cap from Watford Junction (i.e. z1-9 plus WJ) is £13.

His method (if it works using a single Oyster card) brings the cost
down to £7.30. My suggestions cost £8.50 and £9.30.

Specifically, the bus from Watford to Bushey, the LO train from
Watford High Street, or the Met line from Watford Met station options
all come in at £8.50 (z1-9 off peak PAYG cap) - none of these are
*that* complicated, and they all offer a saving of £5 over the cost of
a Day Travelcard from WJ, or £4.50 over the cost of the PAYG cap. OK,
so perhaps that's no big deal, but I reckon it's useful to know about
anyway - with information comes the ability to make an informed
choice, after all.
