Al this has been discussed in the OWC thread in detail some weeks ago as cruiseboy89130 constantly refers to this point in various threads... To go around Africa to Gibraltar takes additional about 10-12 days, to East Med little longer about 14-16 days. If Serenade has do this they have to adjust the 18 day Dubai to Athens plus cancel the 11 day Athens to Instanbul cruise and they can continue as scheduled in Istanbul from June 7th. It does not make any sense to cancel more parts from the UWC.
