You could ask her if she has any suggestions. Also, you could think of some place (s) to go as it'll help with deciding when the times comes. Just my 2 cents!
Good luck :)

If it happens that you're also free that day, just set a definite date, time, venue, how is it going to be.
Eg, ''hey, let's meet at starbucks at Saturday, 2pm, if you arrived first, please sit at a side table of two, or else we will be meeting at there, if something comes up i will contact u earlier.''
