Can anyone tell me if the climate is reasonable to travel from Padang to Banda Aceh from 2nd February onwards? I can spend 20 days. I have seen an itinerary, but I am not sure if I can do it by public transport, any suggestions?

Is it safe for a single female traveller?

This is the itinarary I have seen, it is a group tour (see right below to see the map and the places).
