We love the freestyle aspect of Norwegian cruising and we used it to the fullest. The youngest in our group did not take any dress clothes and that was OK with us. We loved the Escape, loved our mini suite and our steward (Mario) was probably the best ever and we have cruised a lot.
The Escape is huge but very easy to navigate. Our room was very quiet and comfortable. We had the promotional drink and specialty dining packages. That was really great. I really don't think we would have paid for either if not included in a promotion just because the drink package is expensive and the complimentary dining is perfectly fine for us. We did, however, really enjoy those perks.
One negative from me: Many activities are held in Atrium where there is clearly not enough seating. They bring out folding chairs at some events but not all. If you don't arrive at least 1/2 hour early for anything being held in the Atrium (Deal or No Deal, Trivia, Newly Wed game, Perfect Couple, Dancing with the Celebrities, etc.) you simply could not get a seat. In my opinion the Atrium was not a good option for these large and popular activities. We simply missed the enjoyment of some due to lack of space.
