My tip, if you are spending hard earned money. Then dont limit your experience too what your favourite line gives you as a cruising option.
Look further and to other lines, its all there and just as good. You never know, you may find a line to equal your expectation of Carnival
I agree. I have done 10 cruises, 4 of them Carnival but we have been on 4 other lines-RCCL, HAL, Princess and Disney and in February I go on my 11th with Celebrity.
I like trying different lines and besides as long as the cruiselines have competition they will keep improving things-if they don't have competition but have alyal group who keeps cruising with them-there is no need for them to improve things.
Take RCCL for ex. that used the be a great line but in my opinion they have gone down-hill. I think it is because they have such a loyal base of customers-they sale well so WHY should they improve things?
