I decided to take my son on a 4 night cruise to the Bahamas (he's 6) and the rest of my family ended up joining us, which was 9 in all. The check in was very quick even though I did not have my cruise edocs, I had intended to print them out that morning but they were not available on the website anymore. It turns out as long as you have your reservation number and official travel docs then you're ok.
We boarded the boat at around 1pm and headed straight to the Crossings for lunch. Food was great, service left much to be desired. After lunch we went to our rooms to unpack and I have to say, since this was an upgrade from a previous cruise I loved my room. I had a porthole with two twin beds. The general consensus from the rest of my travel party though was that the rooms are much smaller than Carnival and Princess.
The pools are kind of small and they are saltwater just in case that's a deal breaker for you. I would highly recommend the splash pool if you have kiddos, it's the most scenic place on the ship and much quieter than the lido deck, and it's not saltwater.
Lovely views from the porthole. Very little space for clothing, I would just hang everything up. Samll TV. There is a safe in the room. I would not recommend trying to fit three people in one room.
