What I've found is that most people don't want to see a slide show except on rare occasion, no matter what you name it. Most will, however, enjoy a selection—say 8-12 photos—handed around a table loosely or in a small book. And if they really like that and ask to see more, then turn your slide show into a video presentation that they can watch on their television, tablet, or smartphone.
Still keep it short ... no more than 30 photos, about 3-4 second each maximum ... and keep it relevant with photos of things that friends will be interested in: people, signal places, etc. Have well-chosen music or a voice-over track to docent it.
VERY few people will get through a two minute video, never mind a 20 minute slide show, without a real motivation to see it other than humoring their eccentric friend. That is simply the way it is.
