Alright so one night at Aman Tokyo it is (thanks @
Anlun for making me feel more confident about this) , and the 2 nights prior at Hoshinoya! Although I'm not sure I'll ask Aman to pick up my luggage as both hotels are just a mere 4 minutes walk apart... I think it's a good compromise, I'll get to try very different new experiences, and yes I am spending more money than I was planning on but whatever. Gotta live it up sometimes!
Thanks again everyone who helped me planning this, and I'll make it a mission to visit at least one other (non city) Aman property this year
