Good gift for family with older teenagers/adults as children?

I'm a 17 yr old girl, it's for my aunt/uncle and their family (kinda) but more for them. They're in their early 50's
They live in Colorado
They're semi-religious, so no booze, poker stuff, etc.
They take me w/ them on a houseboat every year, so they like that kind of stuff.
The dad does constuction-ish stuff
Mom works for airline
They have a parrot
the dad likes hunting sometimes
…I don't know what else to say.
They're middle class, nice big house.
Any general ideas? Maybe from someone who is that age?
