Havana area on Horizon is much bigger and is at the back of the ship. It has a much bigger pool than Celebration, more deck chairs and two hot tubs. There was always a security guard on duty keeping people out who did not belong there. Celebration had the towel guy checking wrist bands and he was not always around. We also did not get the frozen fruit on Celebration as we did on Havana. We loved Celebration but would not stay in Havana again on that ship.
