which dock in Castries?

Booked a private tour in St. Lucia and got email saying I should look for their representative at La Place Carenage. I had found info on the internet a few weeks ago that looked like Adventure of the Seas docked at Pt. Seraphine so I called the tour company today and asked if they could pick up there. I then called Royal Caribbean to confirm where we dock and they told me La Place Carenage. It took me forever on the phone to get them to understand what information I was trying to get as to which dock, so I'm not super confident in their answer.

Now I'm not sure if I should call the tour co. back and change back to La Place Carenage since that's what the Royal Caribbean rep. thinks?

We just got back from a 7-day RC AoS cruise on Sunday and we docked in Port Seraphine. There were two other ships across the way closer to the craft market, so not sure if PS is the norm or we were there because it was crowded.
