Zanzibar: to Spice Tour or Not?

This post is also available in: GermanA spice tour in Zanzibar is essentially a must-do for travellers, but there are big differences concerning the price and content of the excursions. I paid 10 USD, but I heard from other travelers that as much as 100 USD can be charged. Therefore, it is worth the effort to shop around a bit and compare prices with the different companies offering the tours.
