Dogbowl mentioned being on NCL Getaway Sep 8 -25. This doesn't look like time period for one of their cruises. Plus Dogbowl posted on Sat (Sep 10). So did you mean 18-25?
Well anyway, I have been to Cozumel many times on Carnival and NCL.
For past few years been booking with Aldora. (Aldora.com). They are right down in middle of town. They have several boats, so they can usually accommodate you.
NCL usually docks right downtown, so its only a short walk.
Carnival docks way out, so it's an $8 cab ride.
As to change of time. I have found that when embarking and debarking from same port, ie. Miami, they keep Miami time. If they are ending in different time zone then they change with local time.
Good luck. I won't be cruising until Nov 13 on the Getaway
DEEPLOU, yes, you are right! The dates are Sept 18 - 25. Oops!
I was able to book with Aldora. They were able to accommodate us but it did take some time to confirm that they had enough boats that day.
This is actually our 2nd time on Getaway. Last time (early March, 2016), our ship docked in Coz from 11am - 7pm. We knew we were definitely going to miss everyone's morning dive trip, but we were able to book an afternoon trip with no timing issues. Since our ship will be docking from 8am - 5pm this time, and most dive ops' morning trips leave by 8am, ship time vs. local time became an issue.
NCL doesn't post their policy anywhere. NCL reps (I spoke with 3) were of the view that the ships changed to local time. So did this website:
Cruise Ship Time The dive ops I spoke with thought the ships usually docked earlier than their posted time.
Also, according to that website, Coz and Miami were on the same time zone from November 1, 2015 to March 12, 2016 (the last time I was there). Therefore, there were no timing issues. This time, however, Coz will be on Central Time and Miami will be on U.S. Daylight Savings Time (EDT), which makes the 2 locations different by an hour, I think. It is at about here that I gave up trying to figure it out.
I also booked with West End Divers in Roatan. We did our OW checkout dives #3 & 4 with them from a cruise ship several years ago - crazy, I know. They were able to accommodate our ship time, and they are able to arrange for a "trusted" taxi driver to pick us up and drop us off.
In Costa Maya, we've booked with Doctor Dive. We'll need to make our way there ourselves by taxi from the port.
In Belize City, we were going to book with SeaSports Belize, but changed our mind and we will not be diving in that port. We will instead do the Hol Chan Marine Reserve and Shark Ray Alley Snorkel by Air. They also have a Hol Chan Dive by Air but I'm not willing to take the chance with that.
Some may wonder why we bother going on a cruise if we want to fit in so many dives...the answer is that non-diving family members are coming along. Plus, we've always been cruisers and we like it, although I must admit, trying to arrange diving off a cruise ship is very time-consuming and often difficult.
For those of you going on Getaway in the future, I highly suggest buying the Dining Packages. Some of those restaurants are to die for! Le Bistro's lobster tail is HIGHLY recommended!
