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

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

A particle normally follows など.

を and に are marked as optional (my dictionary puts them in parenthesis).

For tools: フォークやスプーンなどで食べる人もいる。 "There are also people who eat it with things like forks and spoons."

For places: 夏休みはXやYなど(に)行きましょうか。"Shall we go to places like X or Y for the summer vacation?"

Interestingly, my dictionary says that if the particles precede など,　the sentence is given a derogatory meaning. (が, を and は cannot precede など)

箸でなど食べられない。　"We can't eat with the damned chopsticks."

Alternatively I think you can try:

For places: Xのような場所 "Places like X"

For tools: Xのような道具　"Tools like X"

And by extension: XのようなY "Y like X" for other categories of things you might think of.
