Go and enjoy the various sights! That's what it's all about. Take your camera and camera bag with gear. I would be surprised if you got hassled. If your being an "@ss", then maybe.
Take pictures, be respectful and use your head.
Oh, one more thing... leave your bag unattended on the beach, in any country: Canada, US, Brazil, Mexico, UK etc. and you will probably loose it. It's not just a DR thing.
I have the Nikon D40, great camera, durable, greart pics and easy to edit.
