We just returned from our trip on the Adventure. I have cruised eight times and this was simply the best cruise ever!
Even though there were over 3000 people on the ship, the lines were very light. The food was great. The entire staff including our cabin steward were excellent. The ship is a bit overwhelming at first. The shops and bars on the promenade deck were amazing. After a day or two, it was easy to navigate around the ship.
The ports of call were a blast. In Aruba we hired a taxi to take the four of us around the island. It ran $40 per hour but the personalized service was worth it. Our driver dropped us off at Eagle beach and rented jet skis. The sun was hot and the drinks were cold.
