I've been trying to plan an easter holiday, basically I had my heart set on Vietnam, but its just too expensive. So im thinking maybe I should do a couple of week tour of europe, some cities I havent been to before, and was contemplating booking a hotel in 3 or 4 cities, and using interrail to get between them (I haven't decided which ones yet). I quite fancy granada, but beyond that im not too sure. Is interrail the best way of using multi country trains in europe, or are there better alterinatives? I've never travelled long distances by train abroad, apart from a bit in china.
