My husband & I are in our early 60's and absolutely LOVED the Dream! We chose to stay on board ship for most of our 4 day cruise because we just love the ship! Castaway Cay is a paradise in itself. We got there early in the day and managed to snag 2 hammocks on Serenity Bay and enjoyed those until the sun got too hot. The water is crystal clear and we did see one large stingray.
Food? If you go hungry, it's your own fault! It was delicious and much more upscale than the Disney cruise last year. And being able to bring your own liquor on board was great also. Saved us some money, although, for a cruise, mixed drinks were fairly reasonable.
The entertainment was top notch! We enjoyed the Disney Believe on the last night the most.
