We usually have 2 cruises on Quantum class, 1 on Oasis and 1 on Voyager/Freedom classes a year.
And one on Vision class...while Vision class has some shortfalls (you cannot seriously compare cabins on Anthem and on Vision... or Windjammer) we are willing to overlook them due to amazing 12 days Southern Caribbean itins and the fact we do not need to drive to Florida to reach S Caribbeans. Atmosphere is very nice too.
