We did the Freestyle a few years ago on the Pearl and did not like it. The first few days the restaurants had waits, and after that, the wife required me to wake up every morning to make reservations at 7am. I was not alone as there was always a line a few dozen deep when i hiked upstairs to make these reservations.
Some regular NCL cruisers on the ship did say that the wait times and apparent disorganization at the restaurants was out of place, but that one experience left a bad taste in our mouths.
Further, we still say service is better when you have the same waitstaff for multiple nights. I can't say any night on the 9 day Southern Caribbean cruise on NCL Pearl we received xceptional service. Even though we paid a few nights for specialty dining as we thought that we would get better food (we did) and better service (we did not).
We are interested to see how Dynamic Dining will work on RCI. We have booked all our reservations for our January 2015 sailing on Quantum of the Seas and our January 2016 sailing on Anthem of the Seas.
I do like the idea of trying different restaurants and choosing your menu for the evening. The flexibility to dine at different times is nice, in theory. Looking at the showtimes and activities we want to do on the ship, we booked dinner between 6pm and 7pm every night of the cruise.
Those reservations basically put us at the same time as the traditional dining time we normally do on a cruise anyway! LOL!
I guess you can't teach old cruisers new tricks!
