These are great approaches Brenda however there probably are some prospective students that can't make it to campus, right?
In these cases, have you considered full engagement interviews over the phone and web? Some of the schools we work with in the online environment and those where students don't prefer an on-campus visit right away use this technique with great success.
Of course you want them on campus, yet sometimes this 1/2 step goes a long way to motivating them to put the effort into showing up.
