Combining に/で particles with 等【など】(or other "etc." stand-ins)?

Question

I was recently trying to make an **open-ended** enumeration of places in a construction that would require the use of a に particle. E.g.: > AやBに行こう or even: > A[and the like]に行こう Preferably using a stronger indicator of open-endedness, such as 等 (to me や only has a weak implication of other possibilities, whereas here I want to convey the idea of "places like A [or B]"). But then I realised that the combination of に and 等 did not sound quite right, and even if it was, I had no idea how it would go (`Aに等`? `A等に`?)... Thus my question: Can 等 (or a suitably similar word for "and the like") ever be used with a に/で construction? (not necessarily just locations... Tools or "means" as well: `AやBで行こう`)

Answer 1

Nado would double with the other particle most likely. I think the general rule is that multi-syllabic particles tend to before the monosyllabic particles.

AやBなどに行こう。
