When you don't have a computer which I didn't until 2 years ago, I did pre-booking which you can't do on Carnival. They send you the same information that you get over the computer, and you just mail or fax it in. The only time I've been disappointed on shore excursions, was when we we did Carnival, and never again. Just did bookings 2 days ago for a British Isles cruise on the Celebrity Constellation July 19th. That info arrived almost a month ago, but couldn't get to it until now.
