RCI docks at both T#6....a reconverted (and too small IMHO) old freight terminal, and also at T#3. Pax will need to find out which one their ship is docking at.
The parking for T#6 is an open parking lot in front of the ship. T#3 has the garage available...across the parking lot, across the rail tracks, and across the busy street.
RCI uses T#6 the most, I know Serenade docks there. Brilliance is usually at T#3.
I like parking in a garage...but the open parking lot right in front of the ship for T#6 is very convenient. We use that when ship is at #6.
