I've never heard of GIVE either, perhaps it's a typo? Do you mean GIVIT?
Zanzibar is not especially dangerous, and you'll need tio use the usual precautions. Have a read of these tips about travelling in Tanzania (which includes Zanzibar).http://journals.worldnomads.com/safetyhub/country/210/Tanzania
Enjoy the trip.

I am also a solo female traveler and felt safe in Zanzibar, even at night, but I stuck to tourist areas where there were plenty of people when I was out in the evenings. It is helpful to observe the local customs regarding dress - arms and legs should be covered - I wore loose flowy skirts and gauzy shirts over camisoles (it is hot there). Treat yourself to some henna designs if you have time - they are beautiful and not permanent. Enjoy! about 6 years ago
