Universal Port Hotel, Shin Osaka Hotel and Kaneyoshi Ryokan. planning on visiting the aquarium and the ferris wheel together since its near by, definately universal studios japan, dotombori street and also sansuikan bath. since i'll be there for 1 week i was thinking what else i should do there?? any ideas?? and will it be better to get the season pass for travelling since i'll pretty much use the railways for travelling around?? i wana stay at the ryokan cuz i like those japanese style room and aloso would seriously like to try out the tube hotel any ideas which is better??
