A correspondent on another thread suggested that the low tourist numbers in Bulgaria are a result of inadequate infrastructure. i don't see why he thinks that, surely, the need for infrastructure depends on the type of tourist.
If you are the type of tourist who wants everything lid on a plate, a full English breakfast every morning and all inclusive holidays then Bulgaria is probably not for you. Should you prefer a country which is more interested in developing itself and recovering from the ravages of the planned economy then Bulgaria is for you. There are hotels in every municipality and at different quality and price levels. Menus are usually in Bulgarian ad those which are translated provide the same joy which Greek and Spanish translations were providing for tourists fifty years ago.
Bulgarians generally welcome visitors and outside resorts will provide a warmth of hospitality seldom experienced by tourists today. The tourist provides a much needed input of foreign currency and if that is spent in local shops and businesses it provides jobs.and away from coastal resorts it may even save villages.
What Bulgaria does not need are all inclusive resorts, water parks at every turn, road trains which run only in the summer and the party atmosphere which has ruined resorts in Spain and Greece.
