That's a very comprehensive plan for travelers out there. But aside from planning your own itineraries, you can also opt to have a tour guide.
Say for example you're off to Paris and wanted to choose which boutiques to buy items.
Personal shopping in Paris can be easy with an assistant who knows shopping the Parisian way. So instead of getting out of budget with expensive shopping, Paris tour guides can help make your trip enjoyable while having memorable items from shopping in Paris.
Having a tour guide doesn't only mean having someone to give directions and plan itineraries. Some can actually help you have a cheaper yet fun travel.
