......and honest even if it's somewhere I've been several times I always start my ads at least 4wks ahead (not exceeding 6-7). That way no one can complain I didn't give them enough lead time to plan etc if they need it and/or are more of a planner like myself. Though without fail I always get a few "just missed you" texts/emails/pm's. Unless you've built up a base somewhere already I feel like anything less than 2wks notice might be setting yourself up for failure.
