I have travelled through Mozambique in december 2002. Only the southern coastal part. That was already big enough

That was also where the solar-eclipse would occur
Since it is 6 years ago things may have changed a bit. Are you travelling from Pemba to Maputo by air. Seems like a really long distance by road.
I Certainly liked the rural travel route. Very naturel. Never found an island again like in the Bazaruto archipel. No wonder the portugese called it the Paradise Islands
I had no trouble staying in Maputo then. We stayed in a not too expensive hotel and dito neighbourhood. Walking and travelling the city never felt awkward. The hotel had map with a marked area where not to go though. That was the city-parc area. Chance of robbery or such would supposedly be greater there. Being 1.90m and 92kg makes me less attractive prey?
The Tin-house and Railway-station by Eifel. The ZOO with ice-bear home! Markets. Restaurants. Etc. All very nice. We were invited to the board room of
the director at the Tin-house to enjoy the view. I hope the railways from the station are restored to function again. These were then under construction. Thanks to EU support.
Found the local people easy going. Rather glad to meet a foreigner and eager for a chat. Maybe because the civil war was then not so long ago and people were glad it was over? In busy tourist places like Zanzibar people are more into getting somehting from tourist. But according to co-travellers that was still easy going compared to west-coast Africa
I didn't do any super-8 then. Wasn't in the format then

Rather a pity as I can recall numbers of scenes who would have made really nice S8 shots even with a point and shoot.
I did still photography using NIKON SLR and ultra-small MINOX. General landscape/streetscape in public area wasn't a problem at all. Too personal or close-by market scenes here and there gave negative response. Not everybody wants to be in the picture or wants his vegetables and fish photographed either. So better have a conversation first.
Enjoy your stay.
