I did bring the whole book, they told me to bring it with me, but I didn't need to show. Maybe it depends on the fleet if they want to see it or not. You should bring it with you. Are yours that heavy? If they are that heavy and you don't want to carry them around during your vacation then just leave it, tell them you are very sorry in case they ask for it, but definitely bring all your licences with you and then the copies of the last pages.
You will have to hand over your original logbooks later on during ground training.
