Wedding invites, social etiquette?

<It's never acceptable to ask for gift. There are no loopholes to this rule. It's bad form to request a specific gift, and it's considered poor etiquette to mention a gift registry on an invitation or special mailing. It is also not appropriate to ask for a gift of money. To review: it's very poor wedding gift etiquette for the bride-to-be, groom-to-be, and their friends or family to hint for or recommend a gift.>

If wedding guests or friends and family ask where the couple is registered, then it is acceptable to disclose the registry information. Word of mouth is the only traditionally acceptable form of sharing registry information.>

We referred the information about when my DD was married this summer. They had been living together for 4 yrs in a very small house & didn't need or want much. We followed the above guidance & she put a couple of things on a few registries but also included gift cards on these registries as they were options too. Pick some some gifts like sheets/towels, you can likely put them in a carryon for the trip home. You will likely find that most people will ask parents if there is anything you prefer, then if it's the right thing to do the parents can mention gift cards. You are going to get things you may not want but it's a gift which someone took the time to think about & purchase for you so it should be received with the same joy as the money you get.

I believe the social etiquette is to bring a gift but the amount spent depends on what the guest chooses to spend based on their relationship with the couple & what they can afford.
