How to get to 1978

[fbhjr]

One of the things I mentioned to my sister in her birthday letter is that I
plan on going through Cardiff when in Wales and hope to stop by that place
the Tardis has been known to land from time to time.
As my sister gave me a Tardis key for Christmas in 1978 (see the icon I’m
using on this post), if the Tardis is there when I am, I promised to go
back and thank her in 1978.

There are a few flaws in this plan.
1) It is a Tardis key as used by the 3rd and 4th Doctor. To the best of my
knowledge, they have not been seen in Cardiff. Only the 9th and 10th, and
they use different keys. So, my key may not work.
2) Even if I manage to find and unlock the Tardis with my key, it is not
known for being that reliable on getting people to one particular
time/place like Christmas 1978, While Christmas 9178 might be fun, it
won’t get me to my sister.
3) There exists the tiniest chance that a functioning Tardis might not just
be waiting there when I get there. I know, that sounds crazy, but you have
to admit the possibility when making plans.

So, backup plan time.
If I can’t get a Tardis ride back to 1978, how should I get back there?

And, I’ve got to be careful about this. A remarkably high number of
methods of time travel have bad steering.
