Here are a few of the types a port could get put into:
Tour/Sightseeing port:
Any port that I only will go to one or twice I will always try and get on a tour to see as much as I can. Repositioning cruises will usually have ports that are often not visited, on the usual cruise.
I will always make the extra effort to do and see as much as I can in ports like this.
People that don't do this I always shake my head at.
Beach port:
Even though in the Caribbean there are great beaches in every island. Few of the ports will have the beaches very close to the ship.
So after taking a taxi to a beach in an island. It has to be a really good one to make the effort to come back.
The beach everyone goes to in Barbados is one of the only beaches I will always go to. And it also happens to be my favorite of all the islands.
Also St Maarten, as the beach is within easy walking distance, I will usually go into town for the beach.
Internet port:
The internet on the ship is very slow, and also very expensive. So when crew finds free internet in a port it is a treasured find. And if it happens to be fast internet, then even more so. And I will likely come back to whatever restaurant or random hotspot every week to get my fix.
Aruba was this port for me this contract. The restaurant I randomly went to the first time I got to the island turned out to have the fastest internet in the Caribbean, in my opinion. It even seems faster then at home at times.
Have lunch port:
Even when you can eat, upstairs in the guest buffet, it is easy to get bored of the ship food. And even more so when you are confined to the staff mess, for one reason or another.
So going to a restaurant on land is often a highlight of a day.
The Canadian Bar in St. Maarten for Poutine. And Tracy's King Crab Shack in Juneau are places I go back to week after week.
Crew discount port:
Many places in port will offer crew discounts. A good crew deal will keep us coming back week after week.
The Boatyard in Barbados has the best crew deal going. $5 rather then the $20 for guests, gets you use of all the beach chairs etc, a free drink, and a free ride back to the ship.
Also many restaurants will give food discounts to crew. The Shipwreck Bar in St. Thomas always gets me in for the crew burger deal.
Bank, mail, cell phone:
Depending on where you are from. Docking in a port in a home country happens on occasion.
When this occurs, many people will try and get to their bank to deposit money, rather then use the ship wire transfers.
Also their cell phones, which have been basically useless up to that point will work again. Many times you can see crew looking at their phones the night before as we sail toward the port, checking to see if they have reception yet.
Do nothing port:
Some islands, while nice, might just have nothing happening in the port area.
Some ports like this end up becoming a day to stay on the ship, take a nap, etc.
Visit home port:
While it hasn't happened yet, my next contract will include a stop in Vancouver. Allowing me to visit home while on my contract.
Something that is rare and I am looking forward to.
