I always have this problem. I typically book flights, hostels and travel in between seperately. I typically only stay in a place for 2 days so I need a new hostel and mode of transport for each place + a list of places to visit when I get there (with opening times/prices etc.). I usually put all of this into google doc, though simple things like pushing everything back a day are hard.
To me, the most in need of this are gap year travellers i.e. people travelling for a month or more around the world.
I want a rough plan with bus/train times, hostels shortlisted and other notes about how to make it all work together, then I'll probably change the plan if I stay in a place longer or shorter than expected. I'd like to have record of how much I've spend and will spend too. A lot of people in Europe are interailing, which mean they mostly just book trains and hostels - which seems like a simple use case compared to elsewhere.
Existing solutions in general are basically:
- plan everything before hand e.g. get a bunch of receipts from STA travel before you go.
- book a tour (e.g. g adventures), then everything is organised for you
