Cape Town - Despite continuous global economic and political instability, Cape Town Tourism is optimistic about visitor numbers for the upcoming summer season."We are hoping that the strong exchange rate, in favour of traditional source markets, and Cape Town's recent spate of international accolades will be additional contributors to a good season for tourism," says Enver Duminy, CEO of Cape Town Tourism.During September, 60% of all room nights were sold to domestic guests with a further 6% sold to regional visitors from the continent and the remaining 34% to international guests. The sample included tourism attractions, tour operators, car-hire companies and accommodation establishments including hotels, guest houses, B&B’s, back-packers and self-catering establishments. In October 2013, the customary increase in seasonal flights was sparked by airlines such as Virgin Atlantic, Air France, Condor, Lufthansa, Edelweiss Airlines and British Airways resuming their direct flights. Cape Town Tourism will release the results of its next Horwath, HTL survey at the end of November 2013.
