Early Flight @ Tokyo Haneda Airport?

This question came up just recently and I think the appropriate solutions will both work. Myself, I would go to a hotel near the airport the day before and take a short taxi ride to the airport. At the same time, if you use this solution you have to take into consideration how much luggage you have. If you have a lot such that it won't easily fit into the trunk and spare space in the penger area if one of you rides in the front seat, then the hotel bus limo would be the ticket.
