I see! Thanks for the tip. From airport -> hotel via limousine bus i can purchase the ticket @ Airport. But if it's the other way round for return trip, am I able to buy the ticket from one of the Hotel's counter even if I'm not a guest? Wanted to give the limo bus a try this round. Don't wish to make various transfer through train and would prefer to take the bus all the way to nearby destination. Its been about 5 years, a little anxious about revisiting Tokyo.

Probably gonna give the Shibuya Sky a try since its a new attraction; saw pretty positive reviews online too. Forumers, let me know its a sham (if it is) if you've been there.
Planning to visit Shimokitazawa as well, a place that I've always wanted to check out.
