Traveled with family and in-laws.had three rooms. First time
Very relaxing, excellent food service and staff at the London lounge as we ate there every night. Great pizza on the lido deck.
Breakfast gets hectic on Lido deck, suggest to take your breakfast in the Paris lounge, or better yet order continental from room service the night before (don't forget $2 tip for the server).
There is plenty of water fountains on Lido deck so just take a refillable container with a cap, no need to take water bottles (as we learned). Ice tea and various juices as available on many dispensers on Lido deck.
Plenty of hot water and tea and coffee.
On shore excursions, fill up your refillable cup and take it with you rather than pay $$$ for water sold by carnival as you exit the ship or return back. ($4.25 for 1 liter bottle.)
Take advantage of the formal night photo shoots, very nice background and reasonable prices compared to a professional gallery photo shoot (you are dressed for the formal night anyway).
Suggest to purchase the faster to the fun pass - well worth the price.
