This happens on every sailing
of every ship of every major cruise line:

Cruiser A, after checking prices at several of the nation’s largest travel agencies and directly with the cruise line finds they all have the exact same fares on offer. But once on board he finds out that the couple with the exact same cabin next door booked with an  agent who works from home or a smaller agency and got the same (or better) fare along with some nice additional perks (pre-paid gratuities, onboard credits (OBC), free shore tours, etc.) Cruiser A thinks “How is that possible? And how can I find those same deals?”

It’s all in the power of groups.

Groups of Agents

Small, Independent / Home Based agents normally affiliate with what’s called a “Host Agency”. A host agency can often have several thousand independent agents all combining their sales to a point that cruise lines will make sure that the Host Agency and its independent agents have access to the absolute best deals available. That way, a home-based independent agent or small agency can often offer better rates than you’ll find directly from the cruise line or from many of the mega online agencies.

Groups of Agencies

Agencies (including host Agencies) will group together into a consortium such as Ensemble, Travel Leaders, Signature, Virtuoso, and others. Each will have a roster of Preferred Cruise Lines and other suppliers and they won’t necessarily overlap. For example, Avalon Waterways is a preferred supplier for Signature, Ensemble and Virtuoso but not for some others. So if you book your river cruise on Avalon with an agent/agency that belongs to Ensemble or Virtuoso you might be eligible for exclusive extra benefits that won’t be available if you book it through the cruise line or another consortium. And the reverse might be true for other cruise lines.

All of these exclusive benefits work their way down to independent / home-based agents or smaller local agencies through their Host Agency and the consortium it belongs to.

Groups of Cabins

During the course of the year, every seller of cruises will set up group space on specific sailings.  This can be for clients that want to sail together and also want to take advantage of the reduced fares and additional perks/amenities that every cruise line only makes available to group bookings (of usually, eight or more cabins). These agents often have extra cabins under contract than they might need so a person only needing one cabin can take advantage of these group rates and amenities. It’s very possible that someone is holding group space on the very sailing you’re interested in.
