The sunroute seaside station is conveniently located directly above the rinkai seaside station. A life saver when you’ve been out and about all day and return at night. Just go right up to your hotel room from the station. Hungry or thirsty? There’s a Lawson conbi, Aeon depato, Starbucks, Burger King, cafes, italian restaurants and other stores in the same complex.
The downside-no non-smoking rooms... this is a potential issue for people with allergies or respiratory issues. I don’t have any, however, I am a non-smoker and I could detect a lingering smell of cigarettes in my room and hotel elevators. The hotel provides a humidifier/air purifier in the room which helps a bit.
There is a mini fridge in the room that didn’t work very well.
Lastly, the Rikai line is not a JR line so you may have to transfer lines more ofteteb
