you can be a smart traveller by being a responsable one. You can do that by researching before hand the place where you want to go and have a list of the things you need to take with you. On a trip you need just the important stuff, so don't take useless objects with you
When you get the the location be sure you have a place to stay, for example a hotel, a motel or in a tent. If you choose to stay in a hotel or motel you need to have money for the room, but also for the rest of your trip. That's why you need to have in mind how much money do you want to spend in each place you go.
If you want to be a smart traveller you need to pay attencion to a lot of factors, but don't let that ruin your fun.
