Your mileage may vary as my experience was slightly different to ImTempest - we prefer starboard for the view of CC, and on our St Thomas day we also backed in meaning we had a view of the harbour from the starboard side (not sure if this is standard for Disney, as us and Emerald Princess had backed in, but Regal Princess didn't). At St Maarten technically the better view was from the port side but on that day there was ships parked either side which meant there was little to no view anyway.
