Hubby and I are considering The Pearl for a half Panama Canal cruise in April 2020. We've always cruised on Princess before but due to several challenges are considering this ship. But it leads to several questions. We are an older couple - I'm 76 and hubby is 78. Is this a ship for a younger crowd? 1. Do they have "anytime" dining or do you have to schedule your dining in advance? 2. Do they have a non-alcoholic beverage package? Hubby drinks coke and I drink diet Coke? What is the cost? And can it be purchased in advance? 3. Hubby sleeps with a c-pap, do they have distilled water available even at a cost for this purpose? 4. Do they have a covered pool? I can't be in direct sun. 5. What entertainment is there after the shows in the main theater is over? Something other than casino or sitting in a bar. Neither hubby or I are big drinkers. I know there are more but that's enough to get started. Thank you.
