Hmmm, Nagoya isn't looking very good hotel-wise.
Maybe for good reason (not so much to see)?
Maybe we should do just one day there?

I generally don't like staying in one place for more than 2-3 days though, hmmm...

As for Takayama, the photos do look nice and I'm sure I'm a complete Philistine for saying this, but to be honest, to me these shrines all look the same.

Should we maybe go somewhere further away? Maybe fly somewhere else in Japan?
Or take the bullet train to Okayama, Hiroshima or somewhere else?
Or maybe there's some nice place with a beach (provided it's hot enough in the beginning of June)?
Then we could just do 2-3 days of Kyoto/Osaka and then go somewhere else? Maybe skip Nagoya altogether?

I'd also like to have as many SPG nights during this trip, if possible without compromising too much on what we'll be seeing...
