I had the same problem, here is how I justified it. I am a pretty simplistic person although saving and investments are important to me. Many people on this board will try to calculate "the lost potential of money". I found this extremely hard to determine. Most people assume the market or potential of money is always going to increase. Well as we know this doesn't always hold true. So would your analysis be different assuming an 8% rate of return Vs. a -2%...Obviously. I fugured in todays dollars what it would cost to take the next 4-5 trips I want to take. For me they were 1-2 trips to Disneyland (3 nights in a 1 bedroom suite or 2 rooms), a week at WDW staying at Animal Kingdom and a week in Hawaii. I simply picked a week and priced each trips rack rate, added these together and compared to the point cost of joining DVC. For me these 3-4 trips (given the cost of a suite or 2 rooms) was a break even when comparing the points needed for a 1 bedroom villa over this same period of time. I also assumed roughly $100 per day for cooking in the unit for a family of 5 Vs. eating out based on eating Breakfast and Dinner in the unit.
