My wife and I visited Budapest in 2008 for our 25th wedding anniversary. My wife loved it, I enjoyed it. She has always wanted to return and as our 30th anniversary is approaching I was thinking of as a surprise returning but I like visiting new cities etc. What other cities could be easy visited from Budapest. My plan would be to stay 2 nights in Budapest then by train to visit another city (country) around a 3 hour train jouney if possible. Stay 2 nights then return to Budapest again for our final night. Last time we were able to fly direct from Belfast but that route was removed, this time our options are to fly from Dublin (2 hour drive) or one of the London airports.
Thank you for any suggestions
