I work in tourism and live in Alaska. My wife and I also take cruises, and I wholeheartedly agree with the 95%+ cell phone figure. FWIW I've seen as many Leica's as I have Pentax's on tourist necks (1 of each) in the 5 years I've been up here. I see the occasional mirror less body, usually an a6000. Lots of base model dslr's from CaNikon, more point and shoots, and lots and lots of cell phones. The only thing I hate seeing are idiots using their tablets to take photos. It's obnoxious and rude in my opinion but that's a rant for another day...
I consider myself a photographer. I've studied and practiced this craft, this art, for almost 20 years; I have a degree in art and have managed to make it in to juried exhibitions, book the occasional gig, and sell a piece here and here. I understand and appreciate composition and light and the decisive moment. Yet my primarily cameras for travel are my old film rangefinders and my iPhone. I've consistently shot about a roll per day and use my phone for the fill in, family snaps, etc.
I can't for the life of me understand why so many people choose to drag several pounds of camera and lens with them on vacation. For the most part I do not travel with my DSLR unless I *know* I'm going somewhere with the express intent of shooting. For example I just got back from New Mexico with my wife and daughter and for once I brought my kit with me because I knew I was taking newborn photos for my sister in law, taking family photos for a gathering, and going to the ABQ balloon fiesta. I used my DSLR a total of five times in 20 days and took around 1500 photos that got whittled down to about 30 for the newborn shoot, 50 other misc family shots, and about 30 from the fiesta. Of those keepers I probably only needed the DSLR for about 20% of the shots, maybe 5-10% if I exclude the Ultra-wide shots from the Balloons, and overall I have only a small handful of shots that I want to print (family stuff excluded). The juice isn't worth the squeeze for me when I'm on vacation, so I choose to let those 5 of 1500 shots go and use my cell phone. And my film cameras because of course I can't really let them go, can I?
My basic question when gearing up to go out: is this personal or is this work? If personal I'm far more likely to leave the big gun at home or in the hotel and just bring the phone and film.
YMMV
