I see Carnival Spirit has added another round trip Hawaii cruise, Jan. 20, 2012 from San Diego. I assume this means the others are selling well. We're booked on the April 13, 2012 cruise from San Diego and are finding it hard to wait that long- thinking we may have to "fill the gap" with a cruise this fall.
Prices for the Jan. '12 trip are well under what the other two (Dec. '11 and April '12) are selling for.
