Went annually from 2001 through 2010 during April vacation...Boston to Aruba.
For a party of four, we've paid as little as $1700 and as much as $3200 ($425 to $800 pp with tax). Tracked costs closely....we got "good deals" each time. How could $3200 be a good deal? Some years are cheaper than others.
Typically, we paid $2200 to $2600. Always purchased late May, June timeframe.
