Definitely think JY need to expand their holiday programme in Africa. Would love to do Tanzania and a Victoria Falls/Chobe National Park trip which many other tour operators do.
Also European city breaks with walking tours included. Cities such as Prague, Budapest, Stockholm, Gothenburg, Copenhagen, Seville, Porto, Vienna, Bologna, Turin.
More active holidays would be good as personally I am not keen on spending long periods in a coach. which is almost inevitable in places like America.
