In regards to your question on the AB category, you made the best decision to NOT book the Penthouse. We just returned from a cruise on the Pearl and were in the "Amber Suite" 11530 (AB). Our room was located right under the ping pong tables. It was the most disappointing and miserable cruise we had ever experienced! It's very sad to save and spend that kind of money for a much needed vacation to be forced to listen to the booming of people jumping above your room day and night. We contacted the front desk and our concierge many times with absolutely NO resolution. We've sailed many times, mostly Royal Caribbean, and that is what we will return to. Never again will we go on NCL due to their non-concerning attitude. Also, the "Freestyle" dining experience wasn't so freestyle after all. You must make reservations if you want to eat at a reasonable hour (before 9-9:30). If the situation was different, we would have loved our suite. It is much nicer and roomier than Royal's Grand Suites providing a private room for our daughter and her own bathroom...not to mention 4 tv's total! WHat a sad shame they don't have a better solution for these rooms all located on deck 11 which is right under the pool deck. My other family members were in Mini suites and they were perfect for 2 people. We actually would have switched to one in order to have peace and quiet but the ship refused to help us. If you need any further information, please let me know.
