WOW, that was quick.

Would the use of Solver still be required if the preferences were not weighted? I think weighting the preferences would be ideal in a digital world but may just complicate things for her. If possible, I would like to see a simpler sheet with no weights and the maximum number of preferences limited to three but could be modified for one max or two max preferences.

I will ask her how many campers actually submit cabin mate requests. This number could be much lower than I imagined so a free version may be adequate. One more thing I forgot to mention is the number of possible combinations are only half of what you thought them to be since cabin mates are always of the same gender.

Thanks again!
