求助:葡萄牙西班牙两国行程制定,谢谢回贴

本人要去签葡萄牙的申根签证,但在行程制定上有点小问题,行程安排如下:
day1: from UK to Portugal(Lisbon), stay in Lisbon
day2: stay in Lisbon, and then to Madrid by night train
day3: stay in Madrid
day4: from Madrid to Seville
day5: stay in Seville and then to Barcelona by night train
day6: stay in Barcelona
day7: from Barcelona to Lisbon, stay in Lisbon
day8: stay in Lisbon, and then fly back to UK
这个行程安排在Portugal待的时间太短,所以想请问各位Portugal还有哪里好玩,可以让我多加一日在Portugal减少一日在西班牙,另外,坐夜车的行程是算在哪个国家呢,比如说坐夜车从葡萄牙去西班牙?谢谢大家了
