Embarkation is standard - when you check in online, you get a 30 minute window to show up. If you show up outside the window, you go in another line. Passports are check before security. Keys are in your room mailbox. Getting on the ship is much faster now.
Carnival app - not sure why no other cruise has this. Has all activities on the app. What food is available. Chat with your group for $5 for the entire cruise. Can check into dining for any time dining. Maps of decks.
A lot of rooms are smaller and used more efficiently. The main theater is on 2 floors instead of 3. Only some small tables on the outside. The main floor seats are like dining seats, so they can be move around based on the show needs. No tables so there are more seats in a smaller area. There is a bar in the theater.
Cabins were clean and nicely stocked. They are shorter and wider - only 2 cabinet doors instead of 3 - the one missing is the full length one. Sitting area is wider. TVs are large LED - about 42"vs 24" on other ships. Channel selection is not great. Beds were comfortable. Since the room is wider, there is more room beside the beds. Mini fridge in room. No speaker adjustment in the room for public announcements. Thermostat is electronic instead of dial.
Docks at Ocho Rios Beach. Hang sharp left outside port gates towards marina - follow road and entrance is on your left about 500 yards. $3/person. Go to the further half of the beach - less sea grass and people.
