Everything that MarnaLou has said was true for us last June as well. I think the earliest we had to be in class was about 9 a.m., as I recall, and that was just once. We had three classes, spread through the first week of a 10-day cruise, and then several special dinners, and a special galley tour. It's not onerous, although the classes are 3-4 hours long. The only downside for me was that it gave me another chance to eat! We kept our hats and aprons, but lost our towels the first day!
