We will be on Explorer of the Seas in January and will be meeting some other people prior to going through check-in. I have been told that, due to the large number of people in the terminal, it is better to set a meeting place in advance (possibly outside the terminal somewhere). If anyone can recommend a good meeting place, please let me know.
Good question... I have a friend who is driving in to pick us up the morning we get back into port, it would be nice to have a pre-planned meeting spot not too far from the ship as we will be carrying a lot of luggage.
At the actual port there isn't anything other than the terminal building. There are few "landmarks" other than the elevator and escalator.
But I don't think you will have a problem finding your party. Generally, there is a big room where everyone congregates before they start boarding the ship (after you get checked in). This is after check-in but before the photographers and the gangway.
