There are many, many ways to avoid dysentary that do not include expensive hotels.
Pray tell: how does the military in MUCH more crowded conditions avoid it...as well as performing to peak efficiency with high morale?
And since when does "used" mean "high maintenance?" There are PLENTY of 2-4 y.o. vehicles available...even in the DR...that could give YEARS or maintenance-free service. AND plenty of mechanics available to fix them, even in Haiti. At a FRACTION of the cost.
A stripped-down 2.5l diesel D-Max's for a TON less than fancy SUV's...even less expensive than a HiLux. AND tougher.
Cobraboy - totally wrong on the 2nd hand vehicles in Haiti. Have you ever been to Haiti or operated in Haiti?
It is difficult to keep new vehicles on the road in Haiti let alone years of maintenance free service for 2nd hand vehicles in Haiti. You are not talking from experience on this. Just complete nonsense.
