Depending on where you are going to travel, the rules related to how long you can stay in the country as a tourist can vary greatly. Make sure you know the regulations and have a visa (if necessary). Also check that your passport is valid for at least six months after your return date, as many countries require this. And lastly, make sure you know what vaccinations you need to travel safely, a quick Google search and a visit to your doctor will give you the information (and vaccinations!) you need. And remember: If you are going to travel to an exotic country –for a safari, for example–, plan your vaccination so that it is at least a few months before the trip, some vaccines must be administered several times before traveling.
