We are staying three days in munich and three days in Kufstein in april. the reason why is the price in munich for hotels was over 300 euros 15-18th. So i figure a day in Kufstein where else would anyone suggest to explore nearby cities in either austria or germany. I figure in kufstein visit the castle, glass factory, any thing else we should visit. Also can we use our train ticket from munich- to other cities on the same day besides kufstein. any help in this matter would be greatly appreciated.
