Some advice to get from holiday snaps like any tourist to capturing travel photography which will be worth remembering. As nearly everyone has a phone, nearly everyone has a camera moving around. Even better some take a dedicated camera. Most will tell you, that they intend to make precious memories of their trip. Most will have to admit that they mostly take the same images of famous landmarks as hundreds of thousands of them. That's what tourists do.
Now instead of taking these 'holiday snaps' you should go for some travel photography. Aim to make a photo essay that tells the story of your trip. Take images which will have you to remember the routes you take, the people you meet and last but not least the places you liked.
