Bleh. This reminds me why group projects are the worst. There is no accountability on the academic side to make sure everyone is participating.

I don't think there is anything wrong with suggested you'd like an update from the group, and would like to be able to do your part before the holiday / not last minute.

If they aren't responding I'd say they just want to procrastinate or don't care. Probably don't say you'll stop caring, but you can emphasize that procrastinating for the last minute is something that you'd like to avoid as it causes you extra stress, or you won't have time to finish your part. If they did care they'd give you some sort of an update - even if it's saying they are busy now but plan to work on it on such and such date.
