We were thinking about a family trip to Maui next spring -- either over spring break or right after school is out at the end of May. Our date options would either be March 28-April 4 or May 23-30, 2014. If we go in May, we could possibly extend a couple of days, but I'm wondering if airfares are higher around Memorial Day?? From a cost perspective only -- for flights, condo and rental car -- which dates would you pick? I figure weather would be about the same either way, but missing out on whales in May would be one negative for that timeframe.
