Narita airport to Vintage Shinjuku hotel

Hi,
I will be going to Tokyo soon from January 11th to the 16th. What are the most convenient ways for travelling from Narita Airport to Hotel Vintage Shinjuku as I will be carrying a big buggage with me?
What is the weather likely to be (in terms of Degree Celcius) during this period? Any snows? Heavy rains?
My purpose is shopping. Are all boutiques/shops on big discounts during this period? How much discounts do I expect to get usually?

your best bet may be to take an airport limo (bus) from narita to your hotel in shinjuku. its not too dear (3,000yen) and they lug your luggage from stop to hotel entrance. if you take the train, you gotta lug it yourself.

good luck.

oh and you may wanna bring a warm jacket/coat as its pretty cold now. can get up to ~3deg at night. during the days its not too bad but still cold. no snow in shinjuku. if you get too cold, just buy a new jacket! :-p

cheers!
