Both are ABC Islands, exact same itinerary, same month and all. We have to fly in no matter what.
Horizon in the Havana (balcony and and interior room)
Out of Port Canaveral
or
Celebration but no Havana (balcony and an interior room)
Out of Miami
We have been on the Horizon and really liked it. Would be nice to do the Havana, which we never have. Yet, it's difficult to turn down the newness of Celebration and we have teens that would love the water slides and other fun. Havana on the Celebration adds $1k to the trip and doesn't look as nice as Horizon but I could be convinced.
