I booked the Atlantis Water Park from Mariner of the Seas, on the April 1 sailing.  I'm just wondering why the excursion is only 5 hours when we don't leave port till almost midnight? What if we want to stay in the park longer? Could we just get our own cab back to the ship? $200 each is a lot to spend for 5 hours. 

I'm booked on the Star Princess, Voyage of the Glaciers Northbound May 21st. I see that on the last night (which is generally the nicest dinner in the dining room) we are doing scenic cruising from 6-8:30! We are booked for 5:30 dinner which would totally conflict with the scenic cruising. We were hesitant to book 8:30 dining room, but has anyone done this cruise and think it's worth it to change our seating time? I don't want to do the anytime dining, because I like the experience of the choreographed dining room on a cruise. Thanks in advance!
