Long layover at Haneda

The Monorail Suica also isn't a "normal" suica card. It is a limited version issued by Tokyo Monorail, which just like every other IC card works on any train line or bus that takes IC cards no matter the branding or entity that issued it.
Point is, which some people seem to have missed or ignored, is to get an IC card of some type, from which ever ticketing machine you go to first. Others are suggesting that you go to the Tokyo Monorail and implying it is the only/best way to travel out of HND, which you may not need to do. The Monorail is useful if you are going to somewhere on that line, somewhere near Hamamatsuchō station or to Tokyo Station.
The Keikyu line is a better option if you are going to Shinagawa, Yokohama, Shibyua, Shinjuku and other parts of western Tokyo or parts of the Asakusa subway line.

and zenyattamondatta, just because you haven't personally seen or experienced something doesn't mean that it is "out of date or out of whack". Stop it with the personal attacks and claiming that everything someone says who has experienced something you haven't is wrong.

The police thing may be rare in the overall scheme of things (given the millions of tourists to Japan each year), but it does happen. If you want to do tax free shopping, you must have a passport to show the shop and that passport must have the temporary visitor sticker in it.

Yeah the Keikyu line can be very handy for certain destinations. I normally stay in the Shimbashi area and use this as it's a direct service. It can be a bit tricky to understand the way this line functions for those who aren't experienced with the Tokyo system. (trains get renamed and go in different directions)

As you say, Google Maps is an excellent solution to this. It tells you exactly which service to get on.

For the OP, I think the Monorail + Yamanote combo is probably the better option for such a short visit. It's above ground and you see more and it helps you get your bearings.

I'd consider saying the night around the area of Yurakucho, Shimbashi, Ginza area, Have a great dinner, wander the streets, visit a BIC or Yodobashi, head up to Akihabara etc. Then get an early train back to Haneda in the morning.

Well done on the overreaction.

Still recommend going via Tokyo Station from Haneda to Disneyland? If you were big enough to come back and correct something when you got it wrong, it would be better for everyone.

If you don't have the passport with you and police ask to see it, they can and will detain you

On the list of things to tell a first-time visitor, this would/should be pretty low. You’re much more likely to experience an earthquake.

I say this having spent all of my time in Japan on a non-Japanese passport, and also knowing that zenyatttamondatta doesn’t exactly look Japanese.
