We will be in Dusseldorf for Xmas day 2018 and then have 4 days free to travel 'somewhere' ( including returning back to Dusseldorf)
we are looking for something interesting to see/do, perhaps 2-3 hours train travel or say 1-2 hours flying time from Dusseldorf?
( 55+ active couple)
our trip is already locked in other than these 4 days.
in the general area, we have already been to Amsterdam, Bruges, Gent, Brussels, Rhine valley and we will be at the end of a trip to Prague, Vienna, Slovenia, Salzburg, Nuremburg and Spain.
any suggestions- comments please?
we have previously toured southern Germany/ Austria, Switzerland and France ( east,south and central), lots of Italy
