My youngest daughter is in Tanzania with the Peace Corps, my wife and I are going over there the last two weeks of June to see her, we have the standard touristy-safari things planned on the mainland, and our trip includes 3 nights on Zanzibar, we're staying at the Myblue Boutique Hotel, which is way up on the northern point of this island. My daughter and I are both divers, so I'm thinking about booking a trip for one day while we're there. But I can't tell how close the hotel is to the dive sites and/or the operators, and I really don't want to turn a two-tank dive into an all-day excursion while my wife is back at the resort (she doesn't dive). Can anyone assist? And any recommendations on operators would be much appreciated. Thanks in advance!!
