Replying to Walking around/Traveling

Hey so i was wondering what you guys do when your on a vacation and you go to take pictures of a location what do you guys do? do you take your backpack with your equipment or just take your lens and your camera and keep it around your neck???

heres what im doing so you can understand my question more....

I am going on a cruise and we are supposed to get off the boat the first day and go to the Myan pyramids but theres a lot of traveling off the boat and back on then we walk around and im gong to take pictures...

so i am wondering what you think would be best and most ideal... Should i take all my equipment in my backpack or just take my camera and keep it around my lens?
