I don't know whether it has changed or not but it used to be 5775 Yen per night. No, none of the meals are included but there's a 'crew restaurant' downstairs which is slightly cheaper than the regular hotel prices. The good thing about the Excel is their attitude towards AJX and check-out times. You can check-in at 0700 one day and check-out at 2200 the next night and they'll charge you for just one night. For Japan that is pretty good
Apartment prices are far too variable, so I'm not going to go there
