Lots of lines, waiting, poor service follow-through

We looked forward to this cruise for 6 months, but found things off to a rough start upon arrival at the Jacksonville Port-- which was *completely closed* during our assigned check-in time.  When they finally reopened an hour and a half prior to debarkation, everything was very rushed, porters were rude, and the porter we ultimately used for luggage made inappropriate comments in front of my small children.

Once on the ship, there were endless lines to stand in. Lines for food, lines for service, lines for children's activities.... you think you go on vacation to get away from frustration, only to find yourself stressed when your kids can't get into "kids club" within a 15 minute timeframe-- with only two families left ahead of you??

We completely missed the Carnival-provided lunch on Half Moon Cay, due to misdirected signage on the island (which we later pointed out to Carnival employees).  The lunch area is off in the trees, and signs direct you back towards the beach, AWAY from your only food/ restaurant option between breakfast and 6 p.m. Also, no one informed us that vendors on the island only accept cash, and conveniently enough, the Carnival-branded gift shop on Half Moon was inexplicably closed for the day?

We also had a dietary issue on board the ship (family member with celiac disease), which was brought to guest services, who assured me the maitre d' and head waiter would meet me at the main restaurant, to address and remedy promptly. This never happened. I followed up with guest services, who again made the same promises, yet 6 days passed, and NO ONE onboard the ship ever met with us or followed up on guest service's promises. Ultimately, in spite of our cruise price including meals, one of our traveling parties literally ate Caesar salads and frozen yogurt all 6 cruising days.

This trip would have been wonderful, and the locales visited were absolutely jaw-droopingly beautiful. Unfortunately, experiences onboard the ship were subpar, frustrating, and inconvenient, and efforts towards making those stressors right never even materialized. Was highly disappointed with my first experience onboard Carnival.
