Thanks for all your replies - its very helpful.

ColoAvs19 - maybe you should think about a cruise over here! In Australia you only have to be 18 to book hotels and to go on cruises etc - also 18 is the legal drinking age here.

nonrev1 - sorry, my mistake - it was the service directory I was looking at. There certainly are some good value cruise deals around.

mrs767er - it might end up possibly being an eastern Caribbean cruise we take - I think it is going to depend on what cruises leave on the dates we will be able to go but will have to leave cruises from San Juan PR until some time in the future when we have more time. We've never been to the east coast of America so there are heaps of things we want to see and do in Florida (never enough time or money for everything!)

Cruizers Let me know how the Panama Canal cruise goes - I'd love to do that - I was looking at cruises from LA to Miami but we don't have the time this holiday as we would have to cut the rest of our holiday down. I'll have to have a look at the Barefoot Cruises but I prefer the large ships unless the ocean is flat!

Thanks again
