I agree about this one being better for a toddler - I had just thought of that as well. I had been pondering for weeks about how to try to do everything we wanted to do at ports without having to put our 3 year old in a taxi in mexico! We have decided to try & do a western caribbean itinerary in a few years when it would be easier with the kids.
However, with this itinerary I am more concerned about the weather. Before, we we going so far south that cold temps wouldn't have been an issue, but from everything I have read online, CC is pretty much hit or miss in January. It could be warm & sunny (but water is almost always chilly) or it could be cold & windy, and many times the boat can't even dock due to high seas. But, many people have also said that the captain tries his hardest to put us there on the best day weather-wise, even if it means changing the days/ports around. Let's hope for the best!
Regrettably I cannot commit to participating in a FE. I stay super busy and try not to add anything else to my plate unless absolutely necessary in order to keep my sanity!
