Overall, a good cruise. Embarkation was very easy, despite all the bad things I'd read about boarding in San Juan. To be fair, we do have priority check-in from the loyalty program. However, check in took only about 5 minutes and we only had to wait (in seats, with refreshments) for about 20 minutes to get clearance to board. We arrived at the pier around 11:45am and were on the boat enjoying a cocktail before 1pm. So get there early and start your vacation is my advice.
The staff on the boat was excellent, truly great service. The ports of call on this itinerary are great, especially Curacao & Aruba. Having never been to the southern Caribbean before, it's now my favorite part. Besides being very beautiful with great weather, the people were all extremely friendly.
The ship is a little old with some outdated decor. But, she's headed for dry-dock this year I think so that's not really an issue. It wouldn't be for me anyway. The food in the main dining room was OK. Nothing was bad, but some nights were definitely better than others. At worst, it was on par with food at an average wedding. We ate in the specialty restaurant on the last night, and that food was excellent.
We booked another cruise while on board and were considering sailing on the Adventure again (it flip-flops between 2 different S. Caribbean itineraries). In the end, we chose to book the Jewel because of the specific itinerary and because we like the smaller ship. I would definitely consider the Adventure again in the future.
