We're a group of 10 & doing Personal Choice Dining for the 1st time on our 1st Princess Cruise on the Sapphire Princess on 10/15 to Mexican Riviera. I've heard on other cruise sites that we should make advance reservations for dining for each nite as soon as we get on ship. Now I'm hearing that we can only make then one night at a time AND that we probably can't make them around 6:30 - 7:00 when we want to eat, but have to make them before 6 or after 8! This is exactly why we avoided Traditional Dining because we didn't want to eat at those times! The Princess brochures and literature all say "...now you can eat when you want...", but apparently that is not true. Any answers or suggestions????
