Don’t select this cruise if you or anyone you’re traveling with has mobility issues— there are no “gentle” excursions. One passenger referred to them as forced marches. The ship docks way out of the towns for the most part so you can’t return early if you’d like, and 9 out of 10 times you’re looking into someone else’s cabin as there is a ship docked next to you. If you’re interested in the e-bike excursions, also beware; if you don’t book super early you won’t get on them.
There is almost nothing to do if you elect to stay on the ship. The evening entertainment was lame, although the exercise instructor was excellent.
Everyone is unfailingly polite in a very impersonal way, and when something goes wrong the response is very corporate. In our case we couldn’t complete the last three days of the cruise because of low water in the Danube and all Celebrity offered was a $250 credit on a future cruise (which they upped to a.$1,500 credit when my travel agent asked).
Would have been great if we could ever see out our window, but this was rare.
