Princess Ulua runs a fixed week that includes airport transfers, seven nights in a double cabin, three meals a day and up to eighteen dives including two night dives. The schedule also has beach landings and a night barbecue on a desert island, so it is not purely a diving trip. That format suits divers travelling with a non-diving partner, or anyone who wants a week where the boat is the holiday rather than transport between dive sites. Check the season, as the itinerary follows the weather.
