We did something like this as a family when we were deciding on our trip for this summer. I didn't keep it, however, once we made our decision. Each of us (myself, my husband, and both kids (girls, ages 9 and 7) looked through the current itinerary book and we each picked our top two trips. I then used Excel to record price, number of days/nights, on our own meals, etc. We then ranked each trip, and we ended up picking our #2 (our #1 was booked for the dates we needed by the time we were certain we could go). I felt like I learned a lot just doing the spreadsheet, and I found it very helpful.
