Hello,   I am trying to plan a short cruise 3-4 nights in February 2019. I've been on about 15+ cruises. Mostly NCL, then Princess, RCCL, and a few Carnival. I love going on NCL, and enjoyed Princess. I am a fan of larger ships with more action, and newer boats.   My question is the following. Right now for that time frame what works for me is either 1) Celebrity Infinity 2) NCL Sky (been on it before, not bad for a tiny no frills ship), I do have Platinum on NCL 3) RCCL Mariner of
