We have just returned from a very expensive 14 day river cruise from Budapest to Amsterdam on the danube, main and rhine rivers. We had a lovely time, but were surprised by a few things which i had not expected and never heard about so thought i would pass this on to anyone on GN considering such a holiday.
firstly due to bridges, the sun deck was closed with no access for at least 6 full days, with limited opportunity to get outside. The weather was fantastic so being stuck indoors was disappointing.
next the huge amount of locks (70) which meant sometimes long periods down low, close to the wet brickwork of the locks, so no access to the pricey balcony upgrade we had booked. curtains closed, lights on.
finally when parked up for tours in the various towns and cities we were generally parked side by side with other river boats. this meant again curtains drawn, lights on because of the close proximity of someone elses cabin just inches away from your own. and again, no access to balcony./views.
It was our most expensive holiday ever by far, and yes, we did enjoy it, but if you do the same, it might be better to be prepared for the above.
To think that London, or anywhere else for that matter, does not belong to any one demographic
