Could either of these be it? en.wikipedia.org/wiki/Travel_literature en.wikipedia.org/wiki/Imaginary_voyage

Would "Custom" or "Custom Assignments" work?

"Modifies" as in "is attached to". "Only two" implies that he could have stayed there for more than two, but stayed for "only two" instead. If he meant "This was the only place he stayed for two days", then "He stayed here only for two days" would be alright, but "He stayed only here for two days" would be better. Given this, the second option is better if the number of days is what "only" refers to.

"Only two", because "only" modifies the number of days.
