My Europe travel equipment is a Canon S120 P&S, a Samsung WB150 backup P&S, a GoPro Hero 2 and, if all else fails (and it has), an iPhone 6.
The S120 shoots nice stills and 1080p video. It also has a "hybrid" setting in which every time a still photo is taken, it also records four seconds of 720p video and sound and saves it to a daily digest that can be edited later.
The WB150 was my previous-generation P&S, and it's the back-up now. It does ok, and I'm sure glad I had it on this last trip when a big dust spot suddenly appeared on the S120's sensor.
The GoPro's video is crisp and sharp when viewed as a video, but the resolution doesn't look so good when a video frame is captured as a still. The GoPro does have a still photo setting, though, and at 3840x2880, resolution is very good. Downside is that the extreme wide-angle lens creates fish-eye distortion. You can still make nice photos with it, though. My favorite photo of my recent Italy trip was made with the GoPro's still setting. My grandson was crouched down on the ground taking in the Circus Maximus, while violent stormclouds brewed overhead, and there was still direct sunlight on Palatine Hill. Only the GoPro could have gotten all that in.
Here's a video from my Bavaria trip last year. It includes both 1080p and 720p (the four-second "hybrid" clips) video from the S120; as well as GoPro video.
No reason not to take the GoPro -- it's tiny and weighs almost nothing.
