American Cruise Lines review: Stay far away from ACL

The staff was very hospitable, but were not either a) very experienced or b) very well trained. Far more importantly:
1) Our toilet did not work when needed, often flushing in the middle of the night and interrupting our sleep. Texted a message to the hotel manager but got no response.
2) The newly installed captain sailed the ship through seas rough enough to send every item in our cabin that wasn't anchored flying - off tables, off the desk, off countertops. We were literally thinking what clothes we'd want to wear before we put our life jackets. The only way we stayed in bed was by literally holding on to the mattress. Submitted a message reporting this on the ship's app; no response.
3) We discovered that a drawer where my wife had put some of her clothes was infested with mites - too small to see but caused very annoying itching around your face and hair. We both experienced this and actually left the cruise after two nights to wash our clothes (flying from Martha's Vineyard to Boston). After we arrived back home, we spent days trying to get rid of these mites, from washing to insect spray with clothes spread all over the driveway. Ten days later, they're gone.
4) We wrote this experience to "Customer Service" (oxymoron) and, after threatening to have an attorney follow up, received an email essentially saying "not our problem".
There were other problems, but minor in comparison, so we'll let those go.
We've sailed many, many times and never had a complaint. Our ACL experience was a nightmare.
