Budgeting an Unknown Itinerary
I want to travel a few months 3-5 around Europe volunteering next year starting April or May. I then plan to make my way to Vietnam and hopefully spend some time teaching there.
I don't have an exact itinerary (I have a dozen rough drafts). My big question is how do you budget when you don't know exactly where you're going and how long you'll be each place?
Another question is how much of a solid itinerary would you recommend having? I want to go with the flow as much as I can and don't want to be locked into any plans just because I purchased tickets already. But I also don't want to go over budget because I'm scheduling stuff last minute or not taking the most optimal route, doing a lot of backtracking etc.
