Yes you can do a Disney Cruise as an adult without children. Seven days cruising around the Caribbean. The ship had an adults only deck, not a child or Disney character in sight. Missing the Disney experience just wonder round the ship it’s all there and just as you would expect 5*. Different restaurant ever night with your waiters following making it very easy and comfortable. More relaxed dining on one of the top decks should you want a change, or room service if tired after a day sightseeing. Everything on board is 5* highly recommend. Cabins spacious and house keeping pristine, we felt very special and much care was taken to make your experience a once in a lifetime holiday.
