I just checked to see if we had an excursion...yep, called "Auto Safari" (some kind of zoo I guess). When we went to SoAmerica our doctor prescribed Malarone and we had no problems or side effects, no need to avoid alcohol either.
Atovaquone/Proguanil (Malarone)
Good for last-minute travelers because the drug is started 1-2 days before traveling to an area where malaria transmission occurs
Some people prefer to take a daily medicine
Good choice for shorter trips because you only have to take the medicine for 7 days after traveling rather than 4 weeks
Very well tolerated medicine – side effects uncommon
