We often book Tokyo Inn, because they offer standard facilities/services, including luggage storage, breakfast and room facilities (refrigerator, kettle and wifi).
There are 3 Tokyo Inn near Okayama Station, 1 for East Exit and 2 for West Exit.
We chose Tokyo Inn near West Exit of Okayama Station (just opposite to Train Station and Bus Station), mainly because it is the shortest distance between hotel and station. As we take train, we can walk through the bridge for a direction to Crown Plaza ANA Hotel, afterward, then there is an escalator for downstairs at right hand side. Walking across a small road, then we can reach the hotel. It is very safe, even at night.
Another Tokyo Inn at West Exit, among those 3, it is most far away to station.
Tokyo Inn at East Exit, which is surrounding by different shops and people, or you prefer shopping at night, you can choose this hotel. After you buy a lot of thing, you can put it back to hotel first, and continue to shopping again.
