Booking sites have pretty much eliminated the need for travel agents, we can book anything we want online. However, they don't solve the need for booking and creating a complete travel itinerary from a trusted source. We can book flights, hotels, but research is still required to know what you're booking, so you have to spend time reading a travel book, blog, maybe asking friends, hoping that they like to travel in similar fashion as you. To plan and book a 2-3 week vacation with multiple stops still takes a lot of time, not to mention researching food and sites to see.
I want to create a platform where travelers can be connected with one another to recommend places to stay, eat and see for a trip they are planning. Someone planning a trip will be matched up with travelers that have already been there and create a itinerary and suggest places to stay, eat, see and give insights, just like a travel agent.
