How does the epistemology of science apply to:

- planning a vacation
- what variety of pizza to order
- cleaning the toilet

…etc. etc. etc. etc.
Hmmm....
epistemology (

- (countable) A particular theory of knowledge.

Can you please explain why any of the actions you listed would require the use of a theory of knowledge to perform?
Because if you can do these things simply by accepting information provided by others or from provided from past experience, then your question is nonsensical.
Prove
that
science
is
the
only
valid
epistemology.
Easily done.
Science is the aggregate of every epistemology that reliably works. For example, logic, math, empiricism. Anything that reliably works, science accepts.
Therefore any epistemology which isn't accepted by science has not been demonstrated to reliably work.
Right. So do let me know what variety of science I should refer to when I want to get married.
This question is a bit like asking what kind of mathematics you'd perform to discover whether or not you like eating apples. It's simply non-applicable.
I suppose you could turn to epistemology to determine whether or not you know your fiancée actually exists, but deciding whether or not to marry isn't a matter of discovering or determining the reliability of knowledge, it's a matter of personal preference.
Nothing to do with epistemology at all.
…since at least 90% of the worlds population DON’T use an explicit scientific epistemology (because they couldn’t possibly have a clue what it even means)…how is it so many of them lead very successful lives…seeing as how they’re NOT using the ONLY valid epistemology?
Because they use a non-explicit epistemology they've worked out for themselves, most of which are also used by science.
Sure, science uses a clear process of logic and reason, but that doesn't mean that people can't develop a vague understanding of logic and reason on their own. In fact, most people do, and end up using fragments of scientific method every day in their own lives without realizing it.
