This horror happened to us several years ago. We booked a cruise not realizing it was spring break. It was on RCCL Monarch of the Seas. We did not have teens so much as hundreds of young kids taking over the pools, the decks, everything. The noise and chaos were a nightmare. While I understand spring break may bring more children on a ship, I do think the cruiseline has a responsiblity to accommodate ALL passengers and should monitor behavior to some extent, i.e., kids racing across the deck to dive into the pool, etc., screaming through the hallways, and such. They have just as much responsiblity to provide decent accommodation a hotel would, IMHO. I wrote them and they sent us a $200. credit toward a future cruise, but I haven't been back on RCCL since so unfortunately, it went to waste.
