This is going to be a quick and dirty post. Largely because, although we went to Tokyo Disney Sea, we actually didn’t do anything there. Turns out, the day we went, it was the last Friday of Japan’s Spring Break. Every single ride had a 2-3+ hour wait time; every food cart for stinking popcorn must have had an hour long wait, too. Okay, the truth is that we’re not really Disney people. You may be and can handle the lines and the mouse ears and the good cheer. So, more power to you. My one contribution to your experience – these are two links to Japan Disney Crowd Calendars: here (English) and here (Japanese). According to those calendars, we chose a day that ranked a 95 out of 100 on crowd size. I recommend choosing more wisely.
Pictures start off on the Disney Monorail. From Tokyo Station, it only takes about 15 minutes to get to Maihama Station in Chiba Prefecture (fronting Disney). From there, it’s a short walk to the Monorail.
