My wife and my 12 year old son accompanied me on this cruise. We were looking forward to it because we'd had fun on the last cruise. The first cruise was with Carnival, and this time was with Royal Caribbean. To be honest, I didn't notice a huge difference between the two companies.
This was a 3 day cruise, with stops at Coco Cay and Nassau. We flew in from Nevada to the Ft. Lauderdale airport the night before, and then took a shuttle in the morning from the hotel in Ft. Lauderdale to Miami to meet up with the rest of the company. That was pretty painless, I'm guessing the shuttle ride was 20 minutes to a half hour.
The check in process went pretty smoothly, as I had already checked in online a few days in advance, which probably helped.
