After reading the great replies here, I think I may still be a mega-ship fan. Yes, I definitely could do without the huge crowds. But we are early risers, so getting a lounge by the pool has never been an issue. Another non-issue for us, believe it or not, is food; we eat simple meals (oatmeal is oatmeal, grilled fish without sauce, etc.) and as long as the food tastes good is fine with us. We enjoy entertainment options on the bigger ships. We generally do NOT like the usually corny/hokey main shows. However, there are many music and comedy side show options that we enjoy.
One downside of being an early riser for a cruise, though, is that by 10PM I'm wiped out and ready for bed. Sometimes there's an adult themed comedy show at 11 PM; I make sure not to do any of my usual daytime exercising on that day, although it's still tough to stay up. Attending a lecture of some sort in the evening would be like taking a sleeping pill, regardless of the topic.
