Welcome home to dreary Indiana! Glad you had a great time though. I never realized there were so many specialty restaurants on the larger ships. I love sushi too! Our cruise was really fun also and we noticed the same thing you did about the specialty restaurants not being nearly as full as usual. I also noticed the same thing with the spa and other "pay for it" venues on the ship. I posted a review in the Royal Carribean section of the board.
Take care and hope to catch up to you in Indy one of these days!
