Hi Bosuncat,
Here's the answer to all of your questions:
There is not a lot of walking on cobbled streets and steps, it is mainly flat.
Vienna will be fine as it is all flat pavements, you don’t need to go up or down any steps. It will be a panoramic tour followed by a walking tour, but as I have said the ground is all flat and there are steps involved.
In Budapest there are some slopes and steps that the customer will go up at Buda. However there aren’t loads of steps and you can take your time when going up these. While in Pest the ground is fairly flat and there aren’t any steps to climb up.
In Bratislava there is a slope that you will have to walk up in order to get to the castle. However other than that again the ground is relatively flat and there aren’t many steps that you have to walk up and down.
The Vienna & Budapest excursions will take place in the morning while the Bratislava excursion will be in the afternoon. Obviously this can change if the captain deems it to be necessary. And yes lunch will be on board each day, it will be after the Vienna & Budapest excursions and before the Bratislava excursion.
I hope this information is ok, please let me know if you need any more answers.
Many thanks,
Elisa
