Jan,
what time of year are you going??? I went late Sept/Oct last year. My tips for you would be:
Wet Wipes, and hand cleaning gel (like the stuff in hospital) great for cleaning hands as some of the toilets are NOT the best !!! anything to keep you cool and fresh.
You MUST drink plenty of water, some people did not and suffered nasty headaches.
I took lots of mossy stuff but was bitten alive, ended up on antihistamine tabs so might be worth taking that with you if you suffer with bites.
T BAGS as the Tea is not good,
Loose cool clothes.
Plenty of memory cards or film for camera. one lady didnt have batteries so ended up with no pictures as she thought she would get batteries at the airport.
The right currancy one lady had South African Rand.she lost about 50.00 in the exhange rate.
If theres anything else just ask..
YOU will have a GREAT TIME..
Cindy
