Both daughters love Disney. Their guys haven't been there for years, so I'm not sure how much they love Disney.
In our family, Christmas gifts are surprises. I thought everyone else gave gifts as surprises too.

They
expect their gifts to be surprises. We all drop pretty heavy hints, though!
I typically give them gifts. Last year, my middle daughter, aged 26, got the American Girl doll she always had wanted, and was very very happy.

Oldest one got a subscription to a coffee club, so every month she got a new fancy coffee from Green Mountain Coffee.
I try to buy them things that they would not buy for themselves, because they would think it's too impractical.
