Montreal/Budapest Return Traveling

I’ve been trying to throw together a trip for my birthday end of this month. I’m wrestling with going someplace new or returning to a city I liked. The issue in my head is that a couple of these cities (Montreal and Budapest) aren’t that large and I spent a week roughly in each one. Part of me feels I should go somewhere new, maybe like NYC or Vancouver, and that maybe I’ve sort of seen and experienced the major highlights.

Part of the reason for a place like Montreal is that I work for a company where there are some accommodations (hotels) benefits. Unfortunately there isn’t a hotel in Vancouver and the NYC hotels are always fully booked out.

Anybody else wrestle with returning somewhere vs going someplace new? Advice/thoughts?
