This seven day cruise on the NCL Sun featured two sea days and four ports of call: Roatan Bay, Cozumel, Costa Maya, and Belize City. Please note that if you cannot do steps, you cannot disembark the ship at Belize City, even if you are willing to brave the tender process. The ship does not dock at Belize City and the only access to the tenders is by way of a full flight of steps. It's just as well, as most people returning said I didn't miss much anyway. With three other ports, I was bound to sit one out anyway.
The ship is one of the smaller ones in the NCL fleet and there were lots of special offers and discounts for this sailing, making it very affordable. But be aware that unlike the larger, newer ships, the Sun does not feature the latest technology. The NCL Concierge iPhone app does not work on the Sun. Even the entertainment (which often features scaled down Broadway musicals on larger ships), is less elaborate here. Two of the shows were adequate (A Bacharach-themed revue and a rock revue) and the third was a real hodge-podge with no real theme to it. Naturally, NCL encourages you to try it's premium dining spots, but the 'complimentary' dining rooms are good enough. (I have the feeling they are holding back from being amazing so that you'll try the premium ones instead.) The Garden Cafe buffet was fine - if a bit crowded at peak times. As you've doubtless read elsewhere, the standard cabin bathrooms are tiny and the shower stalls even tinier - no room for swinging the proverbial cat - sort of a curtained tube with a shower head at the top. Overall, service was terrific, with the Philippine staff taking the lead - tireless and hard working - always with a smile. I found some of the European staff were a bit less smiley - borderline indifferent - but perhaps smiling doesn't come naturally in Romania.
Activities on board were the usual fare - embarrass your partner games, or gambling. I enjoyed watching Deal or No Deal, something I hadn't seen before on a ship. They offer Friends of Bill W., singles, and LGBT meetings - but curiously only the singles meets were hosted.
The Family Inside is more spacious than the standard inside, and not much more money. Unfortunately, the bathrooms are standard size - small.
