Tips for her Europe sailings

Uniworld currently warns of unusually low water on parts of the Rhine, Main and Danube affecting select sailings.

Where she docks

"In many ports, your river ship is small enough to dock within easy walking distance of the historic city center"; otherwise a motorcoach

If the river is too high or too low

Itineraries may change for water levels or wind; no refund for changes; cancelling because of a change follows the normal penalty schedule

How much walking on the included tours

"A significant amount of walking over uneven terrain"

Low bridges and the sun deck

Not addressed. Sun deck can be closed by crew under low bridges. †
