I'm really excited--I have a work trip to Japan. As part of this trip, I have a few days in Tokyo. Due to work obligations, I will have an evening (March 29) and a morning until about 1:00 (March 30) free. I also might have an evening on March 28, depending on which train I take from Kyoto, but I am not sure about the exact time of arrival. As a huge Disney fan, I really, really want to spend this free time seeing the parks, even if I am very limited in what I see. I have a couple of questions. Which park should I do the evening of March 29 (arriving at about 6:00 pm) and which should I do the morning of March 30? Should I purchase tickets now, before I leave for Japan, or should I wait until I get to Japan? I notice that the tickets are dated. I do not want to risk my dates being sold out. I also understand that the parks close at 10:00. If I leave my evening park at 10:00, would I be able to get back to the Shinagawa area before the trains all shut down for the evening, or would I need to plan to leave early? I'm not interested in being stranded. Thanks so much!
