Is a Schengen Visa valid for The Netherlands, Amsterdam
Recently I acquired a schengen visa to go to Germany for August bank holiday. Its a multi visa valid till 21st Sept 2014. When I applied for visa I gave details for stay in germany only as I had no other plans. But now i'm thinking to visit Amsterdam before my visa expires in Sept. Would I able to use my existing visa for Amsterdam or do I need to get another schengen visa if i go before 21st Sept 2014.
