I've got to agree with the other guy - not a waste as long as she felt she got her money's worth out of the weekend. My wife and I dropped several grand (in total) to go to Ireland for about a week. Loved it and we're planning our next trip now (might be Iceland, Scotland, or the Caribbean - not sure).

BTW - for those asking, the last gas price I heard for boat fuel was around $4.75/gallon. That would mean she managed to blow roughly 336.8 gallons of gas. Or, assuming 16 hours of the boat moving for three days, 7 gallons an hour (48 total hours, which probably overstates the number of hours).

It's a lot of fuel, to be sure - but it's her money. Hopefully she showed the girls to others in the area as well...
