We don't use agents anymore. We were disappointed with our last agent: she didn't snag us any of the extras on our cruise that we booked through her and we met a couple in the same suite class that had a ton of shipboard credit having booked through Amex. So, I always found I could drive a harder bargain directly with the providers on my own.
And booking air for aruba is like calling for a taxi!!
I'm with Tracey though: if there were a ton of people coming down, I'd hand them all off to an agent.
