"In terms of amenities and value for money, Dormy Inns is easily my favourite hotel chain in Japan. The biggest plus is of course the Onsen, with suana and outdoor bath, but they also cater to so many little things: free late hour noodles, free popsicles and treats on the Onsen floor, free coffee, tea (all locations) or lemoade (some locations).
I'm not sure if this is true for other hotels in Japan but I have now stayed at 5 different Dormy Inns and on average check-in has tsken 2 minutes and check-out has been 10-15 seconds."
