I am a first time cruiser and was a bit leery after reading many negative reviews. I had a great time, and will certainly cruise again. I was worried that I was going to get sea-sick, but didn't. It took a day or so for me to get my sea legs. What was worse, though, was after the cruise. It took three days to stop feeling like the floor was occasionally rolling out from under me. It was worth it though.
Embarkation was quick and smooth. Arrived around 12pm and checked my bag curbside. I was on-board with a drink in my hand by 12:30pm. No problems at all.
Went to my room about 2pm and it was ready. I'm so glad I splurged for a balcony - I can't imagine not having one. The safety drill before we left was quick and painless enough (it took probably a half hour or so). I stood on my balcony for the great view of NYC while leaving port. It was awesome.
