For our lifestyle, we have found that the books are useless. Lotus Spa junk and stuff like that. We have yet to use a single one.
SS Norway (12 times) '85 - '97; Radiance OS 06/01; Island Princess 11/04, Grand Princess 11/04/05, Golden Princess 7/21/06, Golden Princess 2/24/07, Explorer of the Seas 12/23/07, Island Princess 11/15/08
We just came off the Saphire Princess and our coupon books were ok. There was a coupon for the internet cafe, the martini bar and bloody Mary drinks - buy one get one. There were two coupons for $5.00 match play at the roulette or black jack table - although we were able to use them at the craps table on the pass line with a couple of the dealers. Lotus spa, buy three pictures get one free, some boutique coupons if you spent over $100.00 that type of stuff.
I know a lot of people don't think this coupon book is that great, but if you are going to buy the stuff anyway atleast you can get more for the same price.
I hope this helps. Have a great day!
