They also have great deals for repeat cruisers we've used them for the last several years and I have nothing but fantastic things to say about them. They're very polite and customer service is amazing (they helped us through a huge snafu with our vacation last year (when FH proposed), including having a couple not come at all and then changing a passenger due to the divorce of another couple). We're going to book our honeymoon through them.
