It's so great to hear that your family had a better experience during this visit; it sounds like it was just about the best WDW experience any visitors could hope for. Other than the few brief cold snaps Florida experienced thus far this winter, they have had atypically higher temps than usual for this year which is great for a family vacation.
Taking trips "off season" is one of my favorite travel tips and indeed, so many enjoyable travel experiences with my family, friends or solo have indeed occurred during shoulder season or otherwise unexpected times. While this is NOT necessarily easy to do with school age children, various schools have "winter breaks" during different weeks than others so it pays to call the resorts and see if your children's breaks occur outside the weeks they have blocked out as "peak" winter getaway time.
The other option is taking your kids on vacation while they miss a few days of school. Depending upon your children's ages and levels at school, missing 2-3 days might not have a huge impact on the work they would miss. Generally this means taking young children out of school, which is not to say early childhood education is not a key time for any child.....I've seen what kind of homework some 1st graders are sent home with,
! If a child's school work can be made up easy enough, it might be very well worth booking the trip.
My sister took my niece and nephew out of school in February to visit WDW when they were young; the rates were better, less crowded as per Host YGM's report. But these vacations did not, and could not continue as they went further along in school. It seems they all had a good time, except maybe for my niece who is 4 years younger than my nephew and so her memories aren't vivid at all. A 2 year age difference might have made a difference but well, that's a type of planning that might likely never factor into travel planning.
If the timing and ages are right - go for it, why miss a great opportunity to save and enjoy the park more. When it comes to your family, why not get the best experiences you can have if the timing is right? So many times I see questions asking when is the best time to vist.........? Quite often I'll reply "anytime" but I know that this won't always work for everyone so if you are limited to just summer break, don't worry about that either - you'll still have an amazing time
I have...summer trips to WDW, fun, fun, fun..........there are other strategies for making that work well too
