Before my travels, I will call ahead and speak with boutiques to see what their current availability is, whether I can walk in or will need an appointment, etc.
When I want to see or try-on something specific, I will give them my travel dates so they can request to have said items set aside for me (or shipped in from another location) when I come by.
In my experiences when calling ahead, SAs enjoying meeting out of town and out of country clients.
Hope this helps in case you do not get a recommendation before both your travel dates
