We just went on a cruise (with more appealing destinations for 8 days) for $600/person. A similar option on the 7 day BYU cruise is listed as costing $2800/person. That's an extra $5k if it's just me and my wife, more if we bring family.
That means I could literally go on a non-BYU cruise, enjoy myself, buy BYU season tickets AND fly into Utah for each of the home games ... Or I could go on this cruise instead.
