Welcome to the group adamki, very glad to have you joining us! Congrats on completing the Grand Slam too! I think you might be the first Gold CC member to join the group, only 3 weeks until check-in day for you.
On the subject of Key West, I have been once and it is a very nice place. I have no doubt that by January everything will be back up and running, they were lucky enough to not take the hardest hit and are even expecting to open the port to cruise ships this week. Unlike the islands they have the luxury of a highway to the mainland so bringing in supplies is a lot different. Not to minimize what they went through, the Keys will take time to recover, but in January things should be back to relatively normal. We are planning to take a hop on hop off tour of the island and stop at the Hemingway House. We also have no definite plans for Nassau though we will at least get off the boat and walk around a bit as it will be my wife and daughter's first visit. CC depends on how much our daughter wants to spend time with the kids club vs with us.
Just a heads up Myka that you won't be able to actually book anything on the ship or any DCL excursions until your check-in date, November 12th. If you are booking excursions outside of DCL then you can do that whenever that company allows you. The only advice I can give is on the ship is to make sure the kids attend the ice breaker session for their club if they are going to spend much time there. I have been told by many people that this is the best way to meet friends the first night. DD12 will be able to join DD10 in the kids club if she wants, or attend Edge. (DD is shorthand for daughter around here) It can be difficult with those ages, especially if they want to stick together but the older one doesn't want to be with the "little kids" and the younger one can't go to Edge. So something to maybe talk about beforehand with them if you think that could be an issue that pops up.
