We have 3 March use year contracts, which work great for our annual trips in May and September. We recently discovered that a March use year doesn't work so well for Thanksgiving and Christmas trips (past the banking window). We are adding on again, thru resale, and trying for a September use year with the new contract. It will be more work keeping track of different use years, but will be a better use of our points going forward for winter trips. I have had no issues keeping track of 3 contracts with the same use year, if you decide to continue with your March use year. We bought all of our contracts thru resale, and got great deals on all of them. It takes longer than buying thru Disney, but can really help you save money.
