Is spending the day at Atlantis really worth it? I have two ds ages 8, 12. Would they love the time and money spent to be able to enjoy the facilities? Are the water slides that great? I can do the excursion for the same amount of money it costs to book a room at CS and enjoy the whole Atlantis experience. Also, how do you get to CS once you have docked? This will be our first Disney cruise and don't know when or if we'll ever get back this way again. I need your guidance. BTW our cruise date is the end of April aboard the Wonder.
