Hmmm, take it or not?

So I'm having an internal dilemma here. I have an awesome Nikon D60 camera,and and extra zoom lense but i rarely travel with it, because I'm so afraid of something happening to it (the camera plus the extra lenses are a BIT pricey). SOOO, do i take it to Vegas and get awesome pics? Or take the stupid point and shoot (that i HATE), but is much cheaper and MUCH smaller? The Nikon with the lenses is quite large and heavy(the ONE zoom lense is nearly a pound alone!), not great for packing around all day, but takes FAR superior pictures. Every time I pick up a point and shoot camera I'm so frustrated with the shutter lag time, and ability for ME to choose what is in focus. I know I can pack it in my carry on, but I'm just not sure about packing it all around!! Brad will say, he bought me this nice, fancy, expensive camera for a reason, use it!! Is he right?
