Wayne,
Thank you for your comprehensive review. I appreciate you taking the time to cover so many areas and share your impressions. I would agree with you on most points. I guess we lucked out and our food in Tapas was quite good as far as buffets go. We were pleased with all you can eat escargots that were so tender. Also we enjoyed the fresh meat/poultry carvings each day. We ate three times in Toscana and had two great meals and one very mediocre. However, we tried different dishes each time. Still can't beat Don Vito's or the new Italian experience on the Seven Seas Navigator.
I guess we didn't have many sunworshippers on our cruise as we never had trouble getting a chaise as well as we were always lucky to have our own whirlpool.
I agree that there is a definite advantage to booking Concierge level and above. (I was not.) In my opinion it is definitely worth the extra money if you appreciate the level of amenities offered by Radisson. If you are more of a mass market line person, you will probably think the levels below Concierge fine.
We didn't have any problem with service, but were most impressed with how much the Maitre'd cared about our feedback and remembered our preference for tables.
It appears you think once in French Polynesia on the Paul Gauguin is not enough, and I couldn't agree more.
