I have never been to Central America, so just do not know this answer. We will be travelling to Panama, Costa Rica and Nicaragua for 3 weeks, staying wherever the wind blows us, and staying in budget hotels. Will be taking my malaria pills and using a deet based insecticide. Are bed nets also in order, or is this over kill? Do travellers actually use these, and is there a usually the means to hang up these nets simply? All information would be greatly appreciated.
