Do you have any ideas for "experience" gifts for adults? Anything you've particularly enjoyed giving or receiving? I'm trying to come up with a Christmas gift idea for my brother and sister in law. They live in a tiny condo, just went through some major decluttering projects there, plus are talking about moving abroad for work in the next year so I'm trying to avoid giving "stuff" at this stage. In years past, we've done things like a gift certificate for a baking class or a gift certificate for a cocktail-making class. I'm on the hunt for some fresh ideas though.
