Recently, My wife Janessa and I sailed on RCCL's Mariner of the Seas-Eastern Itinerary. While I can now say we have two cruises under our belt, this was by far the best we were ever on.
Check in (Day 1)- We flew into Orlando International the day before, so we got a good head start. Check in from the airport was smooth. We waited at the airport for about 30 minutes and were loaded onto a bus to Port Canaveral. (VERY Organized) The drive was about 45 minutes and is the biggest ship in the port. We had two other ships in that day (Carnival Sensation and Disney Wonder.) Upon arrival, we waited on the bus for roughly 30 minutes until being allowed to get off and proceed to checking in. (BE ADVISED, if you plan on parking a car, get there early or it will be a mess.) Checking in is real smooth. You can expect to be on board the ship within 30 minutes and that's with huge lines.
Cococay, Bahamas (Day 2)- RCCL prides on their private islands, and we can see why. There's plenty to do and plenty of food to eat. There are local vendors on the island. If you are a shell collector this is the place for you.(Bring US Currency as Seapasses are not used to purchase local vendor items.)
