So we returned from our Royal Caribben cruise a few weeks ago and it was really.... good!
Partly good, partly bad...
We went of the Mariner of the Seas... their newest ship. Huge ship, some nice bars, lounges and cool layout. There were SO many unsupervised kids EVERYWHERE it was awful. Even in the adults only parts.
Some may say the food is bad, but i thought it was very decent for such a huge ship.
Sure, you could afford it depending on which line you go through and what ship you want. Carnival was described to me as the "KMart" of cruises. Cheap, but a party all the time. RC was next in line in terms of class and actitives. It goes up from there with Celebrity, Princess, Holland America, Norweigan, Raddisson, Cunard, Crystal, etc. Although i am sure you could find some great deals on teh internet for any line. Most of the "stuff" on board is inclusive... most food, entertainment. But unless you go on an ultra-luxe ship/line, alcohol and shore excursions are extra.
