Enjoying the reports Paul. I am a bit bummed to hear about the congestion and the requirements to pre-book the entertainment but with 4500 people I guess it has to be that way. I'll make sure I pre-book for the October cruise but it is going to be a hard task to coordinate times with the rest of the group.

Oh well, from my estimate, based on your numbers, she's getting 39 ft. per gallon at 20 knots. :-D
