A family member just got remarried and I want to send a gift but they are fairly well established and didn't register, also, they have young kids.

I am leaning towards a gift card but thought maybe someone had a lovely idea for a gift. I sort of like the idea of sending something sentimental or personalized but I am at a loss as to what to send. Any suggestions? They are across the country so I don't want anything cumbersome to mail and I am not familiar with their area.
