Hi guys, please give some ideas or suggestions.

Me and my wife will travel to bandung Sept next year. Planning to do 6D5N or 5D4N trip. This is our first time visiting bandung.
We are hoping to spend 2 nights in lembang and 2 or 3 nights in Bandung.
Basically we want to be away from the city for early visiting Dusun Bambu, hot spirings, Kampung Daun, and shopping for the rest of the trips.

I need some tips and suggestions. Will it be okay if we were on our own without a guide?
