Hi Amanda,
I just spent some time with the chapter consultant who is visiting UGA right now. This is her first year, and she likes it so far (of course, UGA is the first campus she's been to at this point). All of the consultants that I've met through the years really enjoyed their work. I know that you can only be a consultant for 2 years, but other than that I'm not sure what other requirements there are.
The consultants I've spoken with enjoy the travel, but don't really like living out of a suitcase all the time. They all seem to agree that the work is fast-paced and can wear you down considerably. However, they all love the job and think it is a great opportunity to help out DZ. So, I guess there are pros and cons, just like with any other job.
If you're interested, I say go for it!

Good luck, and keep us updated!
Love in DZ,
Carrie
