Is it realistic to hit A2 proficiency for a trip to Yerevan in two months?

I’m heading to Armenia for work and need to be able to handle basic daily-life scenarios like ordering food, asking for directions, and greeting people. I'm focusing heavily on oral output, but I'm terrified that my grammar will be so broken it prevents communication. Should I prioritize learning set phrases, or is there a specific way to practice 'survival Armenian' that focuses more on meaning than perfect case endings?
