Not to hijack the thread, but how early can people usually leave the boat on CC? How early does the 5K start?
I am debating about doing the 5K, but I also have a cabana rented. I want to know timeframe to see how much time will be consumed by departing ship, running the 5K, getting back on the boat, showering, eating breakfast, and leaving the boat for the cabana. Cabanas are expensive and I want to get as much use out of it as possible.
When we had a cabana I just got everything I needed, gave it to DH (who doesn't find nearly-5K in the Bahamas sunshine nearly as much fun as I do), and we met at the cabana and I changed into my swimsuit then rinsed off the sweat in the outdoor shower at the cabana.
When I do NOT have a cabana I go back to the ship (where DH and DS are sleeping in until I get there), but that day DS was running with me and we, like you, wanted to get all the time at the cabana that we could.
When I've done the 5K we get off the ship later than many have experienced. I have yet to disembark the ship for the free island 5K before official "everyone can leave" time. Some experience being first off the ship.
Also, I'm slow. If you're fast then you might be able to run, get back, showered, etc, quicker than I would.
Since it varies by sailing, I would play it by ear. If you're getting off the ship later, just consider doing what I did for our cabana day. If your meeting time is early and you think you'll be first off the ship, and if you're fast, then go on back.
OP there's also the room service option. I tend to get some fruit and definitely coffee sent to the room so I can get up and ready and eat at the same time.
