Zoe:
Get your moneybags ready because this is an expensive one.
I don't need that long! Yes I want to make a dive but don't need to go diving for 2 weeks.
i'm also checking to fly to Assomption island first. But, the plane takes 14-18 people so chartering is probably for a few not interesting as well.
looks much closer from Mayotte or Comores to go to Assomption with a smaller plane (smaller distance as well).
If i find out; will advise.
