Hi and welcome Melissa. The first time we went to WDW I didn't know any better and used a package. When we went down a year ago, I booked room only and got my own park hoppers. With 2 little ones, I would suggest using 2 rooms at one of the AllStars. You, dh and two kids in one room and the in-laws in the other. You can get connecting rooms. Then decide how many days you will want to spend actually in the parks. The parks will close early at that time of year, but the crowds will be non-existent. You might want to go to one park in the morning, go back to your rooms for a nap/lunch and return mid-afternoon to a different park. Just be aware that if you get a package, it very possibley will cost you more in the long run. And, the park pass you get with a package expires at midnight on your departure day. If you buy your own park hopper passes, the unused days on them don't expire. We are using leftover days this Aug from our trip in 2001. Have fun planning. These boards are a terrific place to find info.
