I will suggest Metropolitan at Ikebukuro also. It's more convenient if there is airport shuttle station if you have heavy luggages to carry on your return. If you are taking heavy luggages and staying at Shinjuku Prince, probably you need to get a taxi to the Narita Express stn, and that will be a waste of money.
係JR 新宿站係咪有巴士去廸士尼﹖使唔使預早book飛?
~~~ Have, Book or not is not a big promble if u go at low section
同埋知唔知邊度有廸士尼2-day pass voucher 賣﹖
~~~ You can buy in the local tourism agency,Tokyo station(inside)---Near to travel JR to Disneyland ge!
I suggest you travel JR to go Shinjuku because is the most cheaper.But you need to exchange the train in some place....
