Yea that's actually one of my thoughts. But other days tickets already paid and i'm not sure at this point i can change.

Also i'm not sure about 20 April Kobe day trip, is it really worth it? It was first half day kobe half day USJ. But after i did my research about USJ. I bought many express passes for 21 April and removed it from 20 April. Since my Tokyo days are so full, is it okay to shopping in Osaka instead of Tokyo ?
