PQ: "<i>that is janis' rule of thumb but most tourists who do not want to linger half a day in just two sights move at a faster pace - 3 major sights IME is easy to to and some sites like some museums are even open at night.</i>"

Not one of your days has more than two MAJOR/Time consuming sites (And day 3 has only one unless you mean touring the Palace). You have totally proved my point . . .

CONTEXT man!!! I said two major sites, possibly three if they are near each other, and work in additional less time consuming ones around those. And what have you come up w/-- not even that much.

I give up.
