I love Myrtle Beach! It's so beautiful! We used to stay at Myrtle Beach Resort when we would go there from our old hometown in Virginia.
I'm not sure it is appropriate for a travel agency to put places on Airbnb? You mention property managers, that might be acceptable. There is a new feature where you can add additional hosts to an Airbnb listing, but basically what I am thinking is if the owner of the individual condo or rental fires you or otherwise wants to terminate services, they would lose all of the reviews/reservations/etc and have to start from scratch. So at least from my perspective as an Airbnber, I would not allow anyone that kind of authority over my income source. But maybe your owners would? Also, how do you know none of these listings are on Airbnb already? You would not want to create duplicate listings. No one who already has something listed on Airbnb would appreciate that!
I understand why you might want the kind of visibility that comes from having listings on Airbnb - especially in light of the kind of rentals that are available at Myrtle and other East Coast beaches, which are very homey and in the same vein as an Airbnb listing generally. Have you considered reaching out to individual property owners and educating them on the visibility they could get on Airbnb, and then walking them through setting up an account and adding you as the manager by adding you as a host? (If you are the manager...I am confused as to whether you are the manager or the travel agency).
If you are a travel agency, I would think that airbnb is basically your direct competition, unless the service you are offering is like setting the pricing for people or something like that?? Airbnb is pretty straightforward to use for booking a trip, comparing listing, and filtering results to find the kind of place you want, no travel agent required. It is equally easy for a host to manage.
I also think if the listing is typical of other Myrtle condos, you may need to spell out to potential guests that they will be governed by the terms of agreement at said resort location, as many seem to have their own waivers and documents that need to be signed. I would also doubt that such locations would be willing to submit to the terms of the Airbnb Host agreement, which agrees to mediation through the resolution center and may occassionally result in occupancy fees being waived or reduced, etc.
Due to these items, I don't see how it could be practical to do a batch upload of 600+ properties, because there is a good chance that some of those properties would be violating CCRs or other governing restrictions on using a service like Airbnb, some might already be listed on Airbnb, and I would hope that Airbnb would care to have some kind of proof that you have the authority to represent all 600+ properties, control their income stream, and delete their listing if the owner terminates services with your company.
