I think you will LOVE your decision!!! We bought, and thought we were buying PLENTY of points!! Now, less than 6 months later, we are adding on!! Our contract ALSO came with banked points, and we really cannot use our current year's points...so, we rented them out, and put that money in on a NEW CONTRACT!!!!
I am ALREADY planning at least 2 trips to WDW each year. WDW has been our "vacation spot" of choice. Honestly, in our 12 year marriage..we haven't taken a vacation that was not WDW or DL...but, we haven't taken that many of them (about 4 total). This purchase was to FORCE us to take vacations now that we have a 2 yr old DD...she will be gone before we know it....and, I want as much "special" time with her as I can get!!! I think the more you have (points-wise), the more you end up going....and, with three kids, that can NEVER be a bad thing!!!
Lots of airlines run REALLY cheap specials from NY to MCO (so much so that we are really jealous here in PHX). Just get signed up to get emails from them, and START PLANNING!!! Your kids will love it, and you will have lots of wonderful memories with the most special people on earth!!!
Enjoy...it sounds like you got a GREAT contract!!!
