Thank you so much for all your opinions. Seems that YC is winning over Haven. We have tried Haven for the first time few months ago and really enjoyed it. Although, I want to point out that we enjoyed Haven's food and service, out butler was very accommodating, but we didn't like NCL perks and didn't care for the ship - way too crowded everywhere outside Haven.
I do agree, since X raised prices so much for AQ and Retreat, it seems that product is way overpriced.
I think we will give YC a try.
