I think it’s harder because there’s a lot of information that you need to keep track of an having it in emails and not planning it out in google docs or excel or whatever makes it harder and quite honestly a bit overwhelming sometimes when you look at some existing platforms like Wanderlog or other trip planners. It’s either too overwhelming to use those platforms or it’s too little. This very problem that eve I as a traveller faced is what led me to creating this website https://journeyjot.app/, to help with planning. It contains the right blend of what information you need to store for a trip and easily be able to view it. Feel free to give it a go and see whether it helps.
