Hi,
I enjoyed my stay at the Hilton Yokohama in Dec 2023 ( 1 night and 2 days)
I enjoyed the walk along the waterfront and the osanbashi pier ( with beautiful views of the city at night). After a number of visits to Tokyo , this was my first visit to Yokohama and feel it would be good for a few days to visit ( esp with a trip to Kamakura for example). The winter/Christmas decorations and trees in the shopping malls were very good
The Sankeien garden ( a few minutes by train then bus/taxi or walk) is beautiful
Kamakura is also close by ( lots of temples)
Some ideas on things to do can be found here
