What is there to do in Llandudno in the rain?

[LynetteScavo]

DH is going near Llandudno for work tomorrow, and as teenage DD and I had nothing better to do I said he could drop us of in Llandudno for a day out, as we've never been. But now it looks like rain.

It wouldn't be worth driving four hours in the car both ways if it's going to rain...is it?

I mean, its a lovely part of the world, but 4 hours each way for a day wandering round in the rain anywhere wouldn't really appeal to me.
