Where are you dreaming of going?
A place, a time, a vibe, in your own words. “Japan in October” or “somewhere warm next spring” is plenty, and “not sure yet” is a fine answer too.
Where are you with this trip?
So I know whether to send ideas or start getting dates on the calendar. Skip it if you're not sure.
Where should I send my reply?
I'll follow up personally within a day or two. A few optional questions come after this.
Running a quick security check.
