Hi
Whats your budget and is it adults only or with children?
Cruise and have cruised a lot- thoughts
PO gone downhill, Princess still good for families as is Royal Carib, Celebrity as before but a bit more up market, Holland America normally anybody under 50 is in the "kids" club and plenty of Americans on the Carib cruises.
Adults only I love Oceania no dressing up (well not outside of the cabin) first class food and very relaxed.
Money to waste Silverseas & Regent but a lot of very wealthy (posy)people.
Best bet IMO either Royal Carib or Celebrity.
We are doing a Celebrity at the end of the Month
