Sapphire Princess is a great value for your dollar
The Sapphire Princess is a lovely ship that has many amenities available without additional charges. For example, you can use the spa changing facilities which includes the large showers, lockers, steam rooms, hot tub, and secluded adult pool for no charge. If you want to use the hot beds in the Serenity area it is an additional $99.00 for the week; I did choose this option and enjoyed the peace and quiet but would have been happy knowing that you don't have to pay extra to use many of the facilities.
The International cafe is open 24 hours and has really excellent food....no extra charges for the meals there or for the very wonderful deserts! Try the peanut butter chocolate mouse! Twice the ship had a special pub lunch which includes fish and chips/Scottish eggs/Shepherd's Pie/Chicken Curry, check the princess patter for those days.
The casino staff will take the time to teach you how to play the table games.......take advantage of their expertise...it's free. The library has a number of games to play, be sure to bring your Mah Jongg card; they organize games for the guests and have several sets available. Bring a book and take a book exchanges were also available in the library.
Avoid the specialty coffee because the Sapphire has the best "free" coffee I've had on ANY of my 26 cruises.
Don't worry about "run of the mill" food on the Lido deck, it's excellent! Especially if you don't want to do the formal nights in the regular dining rooms, this is a very pleasant option. This is a ship that you can easily have a wonderful vacation and not break the bank
