Thank you godwine! We were actually thinking of staying at Tokyo Prince. I also wasn't sure if it would be too rushed to do both in one day but if you say it's not that's definitely helpful and is what we will plan to do.
I figured the gift shop at the Ghibli museum would be expensive. Would it be cheaper to wait until we reach Odaiba to pick up some Ghibli souvenirs?
Thank so much for the help!
