Ok, heres what I know. Roger has already answered the question about the back area by Horizon/Caribe. It is there, with a bar-like seating viewing the wake, and a handful of tables.
The pool band, Deep Blue and the other pool entertainer, Robert Smith are the best I have head since the band, "Heatwave"years ago. Professional, in tune and played a long time. A real treat.
Saw the paddle tennis, don't know the hours of play, don't smoke so don't know the details of the smoking rules, but one side of the ship is smoke free outside and the other side has ashtrays. On our sailing there were nothing but courteous smokers, so I was not affected at anytime- thats why I didn't take notice of details.
There is a bar out back on the top deck and I think one hot tub.
As for the passport question, no you don't need one, but seriously consider getting one before your next cruise. Makes everything easier including flying. A lot of people think it is expensive. While depending on your personal budget, it may not be dirt cheap, a lot of people would spend that money on a nite out without blinking. Mine was $75 (I paid to rush it 8 years ago) and spread out over ten years it is $7.50 per year.
Your photo ID drivers or non-drivers liscense and an official raised seal birth certificate will suffice. Check with your cruise line's 1 800 number. They are the best source of what they require.
Ter,
Don't worry each little remark that people make. Remember we help each other here, and some of the comments are just that, so you are not disappointed. Almost everything went right. Some of the issures are growing pains and change from cruise to cruise. My brother sailed her on the first Eastern cruise a few weeks ago. When he and I compared notes we recognized a lot of improvements in just 2 weeks.
Have a wonderful cruise, she is a beauty. Roger and I (Roger, I hope you don't mind me speaking for you, but you have written this yourself) didn't have bad times on this cruise. Roger even wrote that he would cruise her again. So would I. Please relax and have the best time ever. Princess has a great product.
