We make one print-on-demand photobook for each year of holiday trips. It's very nice, no worry at all about data getting lost or whatever (of course you can keep your files too) and the process of making a book is also a nice way to curate and go over all the memories again. Making a new book is always a good occasion to have a look at the earlier ones too. You can show it to people without instigating a looking-at-phones party. If you're into photography at all it's also just nice to see them in physical format.
