Yes, you can save a few dollars, but always book a catagory that you would be happy with, thats the least that you will end up in...Sometimes you may even get upgraded, but at least you'd have what you booked. Best of luck.
Yes it is usually cheaper to book a gty cabin. First rule is to be happy with the catagory your chose. Depending how far in advance you booked, you could possibly receive a catagory upgrade. For example, if you book a 6A, you could get a 6B, C, etc...drawbacks...the only drawback is you don't get your choice of location so it could be anywhere, on any deck. We have always had great rooms with no problems.
