When it comes to selecting a camera, you've got a few options ranging from a point a shoot style (mostly replaced by phones these days) all the way up to the top DSLR. Many may feel that to get a great shot a DSLR is required, but they can be expensive and bulky and often require you to carry them, and their accessories, in their own bag. 

I've found that if my camera doesn't fit inside my handbag, or can be put inside a small backpack, then I tend not to carry it with me. Conversely, the lack of options on a phone or a simple point and shoot camera leaves me a little underwhelmed, or limited in the kind of shots I can take.

In this case, your options are a mirrorless DSLR, which are much smaller than a traditional DSLR, but with all of the customisability with lenses etc or a bridge camera. Whilst a DSLR offers more flexibility, they can be quite expensive, and perhaps a little overwhelming for someone wanting to take travel snaps. This is where I believe the 'bridge camera comes into its own.'
