I may spend a month in Madagascar and cannot find conclusive information on the availability of ATMs, banks, or other methods of obtaining cash.
My travel guide specifically mentions Visa instead of Maestro/Mastercard, but this might be a cultural preference of the French author. All my bank cards use Maestro (the default in the Netherlands), and my creditcard is a Mastercard. Preferably, I would like to spend a month in Madagascar and use my existing bank accounts to pay for the trip.
Alternatively, Western Union is mentioned, but to me this is a relatively unknown (and therefore not well trusted) party. Carrying enough cash for two people for a month is also not an enticing option.
Should I try to get a Visa debit/creditcard, get an account with WU, or is it feasible to travel around Madagascar with Maestro/Mastercard and reasonable cash reserves?
